Switching to another mobile operator in 2026 can help reduce your monthly costs and secure better terms, but before changing provider you should carefully check network coverage, tariff costs, the status of any payments on your phone, whether it is unlocked, available discounts and any additional services. Only after that does it make sense to sign a new contract and transfer your number.
First of all, you need to find out which operator provides the best quality of service specifically in the places where you use your phone most often: at home, at work or while travelling. In addition to the official coverage maps of the major networks, it is worth asking friends and colleagues about their experience. Some companies offer free trial periods via eSIM so that customers can test internet speed and stability before signing a long-term contract.
Next, you should compare the tariffs of the main operators and pay attention not only to the base price, but also to the cost of additional lines if you have a family or group plan. Connecting several numbers under one account often reduces the price per line. It is also worth looking at the offers from smaller or prepaid services that run on the networks of large companies and may offer more flexible terms and lower monthly fees.
An important step before switching is to check whether your smartphone has been paid off in full. If you bought the device on instalments from your current operator, you will usually need to clear the remaining balance before changing company or return the phone. Some new providers offer to cover part of this amount as an incentive to join. You should also check whether the handset is locked to a specific operator and, if necessary, submit a request to have it unlocked.
When deciding whether to keep your current phone or buy a new one, consider whether you really need the extra features and upgraded camera offered by the latest models. If your existing smartphone works reliably, you can use it with a new tariff and cut your costs. If you keep your current device, the operator will usually ask you to enter the IMEI — the phone’s unique identifier, which is used to check compatibility with the network and the type of SIM (physical card or eSIM).
If you still plan to upgrade your smartphone when you switch, you need to read the promotional terms carefully: the maximum discount often applies only if you sign up to a more expensive tariff, trade in your old device or meet other conditions. When placing your order, check the chosen storage capacity, colour, warranty terms, method of financing and any restrictions on early termination of the agreement.
Most customers want to keep their phone number. This is done through a number transfer (porting) procedure. Before you start, you must not cancel your current tariff yourself — the line has to remain active until the transfer is complete. You need to make sure your phone is unlocked and, if you have any additional account protection against unauthorised porting, temporarily disable this option. Then, in your online account or via a dedicated service, a porting PIN is generated, which is passed to the new operator together with your account number and, if required, an access code. The process can take from a few minutes to several hours.
Separately, you should check which discounts you are entitled to. Operators often offer special terms for military personnel, veterans, teachers, healthcare workers, students or employees of large partner companies. There are also specific tariffs for people aged 55 and over, although these may have limits on the number of lines or the range of services. Before arranging the switch, it is advisable to confirm your eligibility for the relevant programmes in advance.
Many tariffs include additional services: subscriptions to streaming platforms, cloud storage, spam filtering, loyalty bonus schemes or free in-flight Wi-Fi. Such bundles can be more cost-effective than taking out each service separately, but only if you actually use them. If some of the extras are unnecessary, it is worth considering a cheaper tariff without the add-ons.
Before making a final decision to switch, it is useful to go through the main points once more: check the coverage of the new network, the final cost of the tariff, the unlock status of your old phone, the outstanding balance on the device, the availability of a porting PIN and the terms of the final bill from your previous operator. Only after that should you safely complete the change of provider and start using your new plan without unexpected costs.
