SIM-to-eSIM route
The described replacement from physical SIM to eSIM takes place in the Mój T-Mobile app.
Plans and support
T-Mobile Polska lists subscription and prepaid plans and offers chat with an adviser.
Range and prepaid options
Subscription and prepaid lines both sit within the range, and prepaid customers can top up their balance. Options are arranged at regional and wider global levels, so the amount of data can be matched to where the phone travels. Data comes in set amounts, which makes the size of each option an important choice. The offer also works with the mobile network standard that newer handsets use. Customers can look at the options and pick the one that matches their usage, changing it later if needs develop.
Extra lines on one number
The MultiSIM arrangement lets one main number carry a set of extra eSIM profiles, up to a fixed maximum. This works well for people who want a phone, a tablet and a smartwatch linked to the same line without carrying several physical cards. Individual and smaller business customers can both use the arrangement, which extends to subscription offers in those groups. Since the profiles are digital, no physical card needs to move between devices. The arrangement keeps several lines organised under a single main number, which keeps the set easy to follow.
Roaming rules
Roaming on the network falls under the operator's own policy, which covers roaming used in ways that go beyond normal travel. Customers who use roaming in unusual ways may find their activity reviewed under those rules. Ordinary personal travel use is the expected pattern, so anyone planning long stays abroad should read the policy before relying on roaming for daily work. Keeping normal use in mind helps avoid trouble with the operator's rules. Clear personal travel habits keep the arrangement in line with the operator's own expectations, as set out in its policy.

Frequently asked questions
Does an eSIM replace the physical card in the phone?+
An eSIM removes the need for a physical card, because the operator's profile is stored digitally inside the device. The same number can then be used on more than one device, which gives owners flexibility when they change handsets or add a watch. Setup is a digital process, so there is no card to swap in or out.
What types of customers can use the eSIM service?+
The technology was first aimed at corporate customers and later reached individual customers and smaller businesses as well. Subscription offers aimed at those groups are included, so people with a personal line or a small company plan can take part. Access is therefore not limited to large firms.
Are smartwatches part of the MultiSIM arrangement?+
Smartwatches with their own mobile connection are part of the arrangement, and the offer is aimed at owners of those devices. A watch can take one of the extra profiles attached to the main number, so the wearer stays reachable without a phone in hand. This gives wearers a practical way to keep their own line.
Does the arrangement work well for people who travel often?+
The arrangement mainly addresses carrying several connected devices under one number rather than roaming itself. Frequent travelers can still use the roaming rules the operator sets, including the operator's policy for roaming services. Reviewing those rules before a trip keeps the plan aligned with personal needs.
