Switching mobile provider
Switching your mobile provider is easy – in most cases, you hardly need to have any personal contact with your old provider at all. Usually, it is enough to choose your new plan, let the new provider know you want to switch, and they will handle the move and cancel your old service. However, keep in mind that the process can vary depending on which provider you are moving to, the terms of your current bill pay contract, and whether you want to keep your existing mobile number. On this page, we explain how switching between providers works in Ireland and offer advice on the different steps involved.
How to switch provider
- Check your contract status: Find out if you are still “in contract” via your provider’s app or by logging into your online account. If you are on a fixed-term bill pay plan, you can either wait until it expires or pay an early termination fee to leave early (more on this below).
- Notice periods: If you are on a 30-day rolling contract or your initial commitment has ended, you generally still need to give 30 days’ notice to cancel. If you are keeping your number, do not cancel your service with your old provider yourself. The porting process handles this for you. If you cancel first, you may lose your number.
- Choose a new plan: Find a provider that suits your needs. Decide whether you want a SIM only bill pay plan (usually 30-day or 12-month terms) or a prepay deal (where you top up as you go).
- Keep or change your number: Decide if you want to keep your current 083, 085, 086, 087, or 089 number.
- Start the “Porting” process: If you want to keep your number, you don’t need to cancel with your old provider first. Simply contact the new provider. They will ask for your Account Number (which you can find on your bill or app) if you are on bill pay. If you are on prepay, they will simply send a security code via SMS to your phone to verify the switch.
- Complete the order: Provide your details on the new provider’s website or in-store. Once the switch (porting) is initiated, your old service will automatically be cancelled.
If you want to keep your existing number
Moving your number is called “porting”. To do this, you simply tell your new provider that you want to port your number.
- For bill pay: You will need your account number from your most recent bill.
- For prepay: You usually just need your mobile phone and the ability to receive a security SMS to confirm the switch.
Please note! Porting usually happens very quickly, often within a few hours, but it is best to do it during business hours (Monday–Friday) to avoid delays over the weekend.
If you do not wish to keep your existing number
If you want a fresh start with a new number, you should contact your current provider to cancel your service, keeping your 30-day notice period in mind. You can then simply sign up as a new customer with your chosen provider. It is a good idea to time the end of your old contract with the start of your new one so you aren’t paying for two plans at the same time.
Do I need to unlock my phone if I switch provider?
By 2026, the vast majority of mobile phones in Ireland are sold unlocked as standard. If you bought your phone on a bill pay contract or directly from a manufacturer in recent years, it is almost certainly ready to accept a SIM from any network.
The only exception might be older devices or specific prepay handsets purchased several years ago. If your phone happens to be locked, you can request a Network Unlock Code (NUC) from your current provider. Most Irish networks now make this process very simple via their website or app, provided you’ve met minimum requirements (such as a specific total top-up amount for prepay customers).
If you’re using an eSIM, your device is likely already unlocked and you can simply download your new provider’s profile to get started
Can you switch to another provider during the contract?
Yes, but it may cost you. If you are still within the fixed term of your bill pay contract (e.g., the first 12 or 24 months), you are technically liable for the remaining months.
If you want to leave early, you can request an early termination fee. Once this is paid, you are free to move. If you received a “free” or discounted phone as part of your contract, the cost to leave early might be higher as it reflects the remaining subsidy of the handset.
How much will you pay for an early termination fee?
The fee is typically the remaining monthly charges left on your contract. Most providers offer a slight reduction (often VAT-exclusive or a 2–5% discount) because the payment is made upfront.
Tip! Always check your specific terms and conditions. Under ComReg rules, providers must be transparent about these charges.
Which provider should I switch to?
Finding the right fit depends on what matters most to you – whether that’s lightning-fast 5G speeds, reliable coverage in rural areas, or simply the lowest monthly bill. While 5G is now the standard across Ireland, signal strength can still vary once you leave the larger towns and cities.
If you’re looking to cut costs, it’s worth considering digital-only brands or MVNOs (Mobile Virtual Network Operators). These providers don’t maintain their own masts; instead, they “piggyback” on one of the three main Irish networks. This allows them to offer highly competitive SIM only deals while providing the exact same coverage as the bigger players.
Before you make the jump, always use your Eircode to check the provider’s coverage map. This ensures you’ll get a solid signal exactly where you live and work.
