Ireland – Landlines and Mobile Phones

What are the international dialling codes for Ireland, and what are the area codes for the most popular expat destinations?

Ireland’s assigned country code is +353. When placing a call out of the country, you use the international access prefix 00, and the trunk prefix for domestic calls is 0. To reach an Irish number from overseas, drop the leading 0 from the area code and add +353 in its place. For example, a Dublin number that appears locally as 01 234 5678 would be dialled internationally as +353 1 234 5678.

Area codes apply only to landline calls — when ringing an Irish mobile number, no area or city code is needed. However, calls placed from mobile phones and certain VoIP platforms always require the complete number including the area code. This means that even if you are physically in the same city as the person you are calling, you must dial the full number from a mobile phone.

The length of area codes in Ireland varies depending on location. Larger urban centres such as Dublin use shorter codes, whereas more sparsely populated rural regions use longer ones — an arrangement that supports a consistent national numbering plan across varying population densities.

The table below lists the area codes for the major cities and regions most commonly associated with newcomers and expats:

Ireland’s emergency number is 999, though 112 will also connect you to the emergency operator. Both numbers are free to dial from any phone, including prepaid mobiles with zero credit. For the authoritative national numbering plan, refer to the ComReg website.

Who are the major landline providers in Ireland, and how can you contact them?

Eir is Ireland’s largest fixed-line provider, offering services to both residential and business customers. As the historic incumbent operator — previously trading as Eircom — it owns and maintains the core copper and fibre infrastructure across the country. Eir is frequently regarded as one of the most comprehensive options for broadband and home phone packages in Ireland, given its high speeds, competitive pricing, and the variety of add-ons available, including TV, mobile, and enhanced calling packages delivered across one of the broadest networks in the country.

The table below outlines the main fixed-line providers and their contact information. Always verify tariffs and plan details on each provider’s official website, as pricing is subject to regular change.

For many years, the Open Eir copper network formed the backbone of landline telephony and early internet services in Ireland. With the nationwide rollout of full-fibre broadband now well underway, dependence on copper is declining rapidly, and Open Eir is actively converting its network to full fibre. If your current connection runs over copper, your voice calls will be analogue; once you transition to a fibre line, calls become digital and are routed through the router supplied by your service provider.

It is worth noting that certain older non-geographic number ranges, including 1850 and 1890, have been phased out in recent years as part of efforts to simplify dialling and improve cost transparency for consumers. Always confirm current plan details and tariffs directly on each provider’s website. A complete list of licensed operators is also maintained on the ComReg website.

Who are the major mobile phone providers in Ireland, and how can you contact them?

Three mobile networks own and operate their own infrastructure in Ireland: Eir Mobile, Three, and Vodafone. Alongside these, a number of Mobile Virtual Network Operators (MVNOs) — including 48, GoMo, Lycamobile, An Post Mobile, Tesco Mobile, Virgin Mobile, and Clear Mobile — lease capacity from one of the three main networks and typically offer lower prices, though sometimes with a reduced range of perks and services.

Vodafone generally offers the broadest national coverage in Ireland, with strong 4G connectivity across the country. Three also provides extensive 4G reach, covering 96% of the population. In broad terms, Three prioritises maximum speeds and wide geographic reach, Eir delivers the most consistent 5G connection quality, and Vodafone represents a balanced choice for everyday use. Before committing to any provider, it is strongly recommended to use the ComReg coverage comparison tool to assess signal quality at your specific address.

According to Statista, over 90% of the Irish population has access to 4G coverage. Meanwhile, 5G remains concentrated primarily in the larger cities — Dublin, Cork, Galway, and Limerick — and is still expanding. In rural areas, signal quality can vary considerably; many residents choose their provider based on which network delivers a reliable signal at their address rather than on price or data allowances alone. Using ComReg’s coverage comparison tool before signing any contract is particularly advisable for those living or planning to live outside major urban centres.

For up-to-date pricing, always consult each provider’s official website directly, as offers are subject to frequent change. As of 2025, prepaid (pay-as-you-go) plans start from roughly €10–€15 per month for basic bundles, while postpaid SIM-only contracts generally begin around €20–€35 per month — though these figures should be verified with providers before making any decisions.

How do I get a landline connected in Ireland?

Arranging a home landline in Ireland is a manageable process, though in most modern households it is now sold as part of a broadband package rather than as a standalone service. Whether you own your home or are renting, the steps involved are broadly the same — although tenants should review their lease agreement before arranging any infrastructure work on the property.

The typical process for setting up a new landline connection is as follows:

1. Check availability at your address. Use the Eircode or postcode checker available on provider websites such as eir.ie, virginmedia.ie, and vodafone.ie to find out which services — fibre, cable, or copper — can be delivered to your property.
2. Choose a provider and plan. Review fixed-line and bundled broadband-plus-phone packages from the main providers. The most widely available option is a combined broadband and phone bundle, which typically includes line rental and a calls allowance, and sometimes TV as well.
3. Contact the provider. You can apply online, by phone, or by visiting a store in person. You will need to present identification documents such as a passport or national ID card, along with proof of address, and select the package that suits your needs.
4. Schedule installation. Where a new line must be installed or existing infrastructure needs to be assessed, a technician visit will be booked. Standard installations generally take 5–15 working days; more complex rural installations may require additional time.
5. Activate your service. If you are transferring from another provider, the new provider will typically manage the switch on your behalf — a process that usually takes only a few days and is carried out at no extra cost.

If you upgrade from a copper line to a fibre connection, your voice calls will move from analogue to digital, routed through the router supplied by your provider. Any devices currently connected to your phone line — such as security alarms, personal care devices, or medical alert systems — must be checked for compatibility with a digital line. Your provider can advise on what steps may be required during the transition.

For standard residential connections in Ireland, no deposit is generally required, though credit checks may be carried out for postpaid contracts. Confirm all documentation requirements and any installation fees directly with your chosen provider, or consult ComReg’s consumer advice pages for impartial guidance.

How do I get a mobile phone SIM card or contract in Ireland?

Obtaining a SIM card in Ireland is a straightforward experience. Prepaid (pay-as-you-go) SIMs are available from all three major networks and can be purchased on arrival without needing a local address or established credit history, making them the obvious starting point for new arrivals. Monthly postpaid contracts demand more documentation but typically offer better long-term value for settled residents.

Here is how each route works:

1. Buy a prepaid SIM. All three major networks have physical store locations throughout Ireland, and SIMs can be purchased with immediate assistance. Dublin Airport and other points of entry also have retail outlets selling SIMs from Irish providers. Prepaid SIMs can additionally be ordered through providers’ official websites and shipped to an Irish address.
2. Activate the SIM. The majority of SIMs activate automatically once inserted into your handset. Depending on the provider, you may need to complete a brief online registration or send a short text. Credit can be added in shops, online, or through the provider’s app.
3. Sign up for a postpaid contract. To take out a monthly bill-pay contract, you will need to visit a store or apply online, presenting a valid form of photo identification — such as a passport or driving licence — along with proof of an Irish address (for example, a recent utility bill or a letter from an employer or landlord) and Irish bank account details for direct debit.
4. Consider an MVNO for more affordable options. Providers such as Lycamobile, Tesco Mobile, Virgin Mobile, and 48 all operate on Three’s network and offer low-cost prepaid plans that are well suited to budget-conscious customers.

The process in Ireland is relatively accessible compared to many other countries. Unlike certain European markets where SIM registration laws require biometric verification or formal residency proof even for prepaid cards, in Ireland a basic prepaid SIM can be purchased and used straight away. Tourists and recent arrivals without a permanent address can use prepaid SIMs without issue, whereas postpaid contracts typically require proof of Irish residency and a local bank account. While prepaid top-up plans can work out less expensive overall, monthly contracts offer advantages such as subsidised handsets, EU roaming entitlements, and unlimited data options.

The majority of Irish mobile providers include free EU roaming as standard, allowing calls, texts, and data to be used across EU member states without additional charges. Always read the terms carefully, as roaming allowances may be subject to caps or fair-use policies on certain promotional or unlimited-data plans.

How do I pay my telephone bill in Ireland?

Telephone billing in Ireland follows a monthly cycle for postpaid contract customers and an on-demand top-up model for prepaid users. The range of payment methods is broad and broadly familiar, though there are a few Ireland-specific options that are worth being aware of.

The most common payment method for postpaid customers is direct debit, whereby the amount due is drawn automatically from your bank account each month. You will need to provide your account details to the provider when signing up; this is usually set as the default payment method when taking out a contract.

You can also pay your bill online using a debit or credit card by logging into your account through the provider’s website or mobile app. Bank transfers — moving the amount owed directly from your account to the provider’s — are accepted by most operators as well. In addition, many providers accept payments in person at their retail stores or at An Post offices (Ireland’s national postal network), which serve a utility-payment function similar to how Correos offices are used in Spain or La Poste in France.

For prepaid mobile users, credit can be topped up at convenience stores, supermarkets, newsagents, and petrol stations throughout the country, as well as online or through each provider’s app. Most providers also offer an automatic top-up facility, allowing your balance to be replenished automatically once it drops below a pre-set threshold.

Failure to pay on time may lead to service suspension, though under ComReg rules providers are required to give adequate notice before cutting off a service. If a billing dispute with a provider remains unresolved, you can escalate the matter to ComReg’s consumer complaints process. Independent consumer rights advice is also available from the Competition and Consumer Protection Commission (CCPC).

Are there any practical tips for using phones in Ireland as a newcomer?

EU roaming: Most major Irish operators provide free roaming across EU member states. Be aware, however, of potential data caps, speed throttling, and any exclusions that may apply to special promotions or unlimited data plans. If you intend to travel within Europe regularly, confirm your plan’s roaming conditions in advance — this is especially important if you are on a budget or promotional tariff.

Porting your number: Moving between networks in Ireland is a straightforward process. You can retain your existing Irish number by requesting a PAC (Porting Authorisation Code) from your current provider. Number transfers in Ireland generally complete within one to two working days of the PAC being issued. If you are arriving from another country and wish to keep a foreign number, note that most Irish providers are unable to port international numbers — the most practical solution is to keep the foreign SIM active on a second unlocked device, or to use a VoIP service for that number, while using a separate Irish SIM for local calls.

eSIMs: Three and Vodafone are the primary providers in Ireland with full eSIM support for postpaid and pay-monthly plans. An eSIM lets you activate a local plan digitally without needing a physical SIM card, which can be especially convenient if you arrive with a compatible device and want to get connected immediately upon landing. Verify your device’s eSIM compatibility before depending on this option.

Rural coverage: A significant proportion of Ireland’s population lives not in cities but in small towns, villages, and rural areas — including isolated farmsteads. Reliable communication is therefore a genuine daily necessity, and it is common for people in these areas to choose a provider based purely on which network delivers a usable signal at their home rather than on price or data allowances. Before relocating to a rural location, examine the coverage maps for all three networks using the ComReg coverage comparison tool or mobilecoverageireland.com.

Wi-Fi calling: With Wi-Fi Calling activated on your device, you can make and receive calls over any Wi-Fi connection even when there is no mobile signal or indoor coverage is poor. This feature is particularly valuable in rural settings or in older stone buildings where signal penetration tends to be weak. Both Vodafone and Three support Wi-Fi calling — check with your specific provider to confirm whether your handset is compatible.

Emergency services: The primary emergency number in Ireland is 999, but 112 will also connect you to the emergency operator. Both work from any phone regardless of credit or SIM status. Knowing both numbers is especially useful for those living or travelling near the border with Northern Ireland, where 999 is the standard emergency number.

Directory enquiries: Directory enquiry services in Ireland operate across the 118xx number range, with various commercial providers offering different services within this range. Commonly used options include 11811 and 11850, though charges apply. Check with your provider for their recommended directory enquiry number.

Frequently asked questions

Can I keep my foreign phone number when I move to Ireland?

Most Irish mobile providers are unable to port international numbers onto their network. The most workable solution is to keep your existing foreign SIM active on a compatible unlocked device — or on a roaming-enabled plan — while obtaining a separate Irish SIM for local use. VoIP services such as Google Voice, or a local number issued by your home country’s carrier, may allow you to maintain access to your original number at low cost.

Do I need a local address to get a SIM card in Ireland?

For a prepaid (pay-as-you-go) SIM, a fixed address is not usually required — you can purchase one at the airport or in a shop with just a valid form of ID. For a postpaid monthly contract, providers will generally require proof of an Irish address, such as a utility bill or a letter from an employer or landlord, as well as Irish bank account details. New arrivals who have not yet secured permanent accommodation are typically better off starting with a prepaid SIM and switching to a contract once settled.

How long does it take to get a landline connected in Ireland?

For most properties in urban areas where existing infrastructure is already in place, a new landline — typically sold as part of a broadband bundle — can be activated within 5–10 working days. In rural locations where new infrastructure must be installed, lead times can extend to several weeks. If you are moving between providers rather than setting up a completely new line, the process is faster and usually takes only a few days, with the incoming provider managing the transfer on your behalf.

Which mobile network has the best rural coverage in Ireland?

Vodafone generally holds the broadest national coverage footprint in Ireland, with strong 4G availability across the country. That said, signal quality varies considerably from location to location, and some users in rural areas report better performance from Eir while finding Vodafone patchy in specific spots. The most reliable approach is to consult all three networks’ coverage maps for your particular area before committing to a contract. The ComReg coverage comparison tool at comreg.ie lets you compare all three networks side by side using your Eircode.

Is 5G available throughout Ireland?

5G is currently available in Ireland through Vodafone, Three, and Eir, primarily in major cities including Dublin, Cork, and Galway. Eir Mobile holds the largest 5G network, covering approximately 70% of the country across all counties and 322 towns and cities. In rural and less densely populated areas, 4G remains the dominant standard, and coverage in very remote locations can still be inconsistent.

What is ComReg and how can it help me?

ComReg — the Commission for Communications Regulation — is Ireland’s national regulator for telecommunications, radio spectrum licensing, and the postal sector. It provides free consumer advice, publishes a directory of licensed operators, offers a coverage comparison tool for mobile networks, and manages escalated complaints against telecoms providers. If a dispute with a provider cannot be resolved through the provider’s own complaints process, ComReg is the appropriate body to contact. Full details are available at comreg.ie.

Can I use my Irish SIM when travelling within the EU?

Yes — most Irish mobile providers include free EU roaming as standard, meaning your calls, texts, and data allowance can be used across EU member states without incurring additional charges. However, certain plans — particularly lower-cost or promotional tariffs — may impose fair-use limits on roaming data, and some unlimited plans could apply speed restrictions when abroad. Always check the specific roaming conditions of your plan before travelling, particularly if you are planning an extended stay in another EU country.

Are there budget mobile options in Ireland for new arrivals?

Yes. Ireland’s MVNO market is competitive and offers a range of affordable alternatives to the three main networks. Lycamobile, Tesco Mobile, Virgin Mobile, and 48 all operate on Three’s network and provide cost-effective prepaid plans that are well suited to those watching their spending. GoMo operates on Eir’s network and offers a single, keenly priced SIM-only plan. Lycamobile in particular provides competitive international calling rates with bundles covering a broad range of destinations, making it a practical choice for those who need to stay in touch with family overseas.
