Pros and cons
T-Mobile Polska
Pros
- Two billing styles in one place: contract and prepaid covers both a prepaid card and a contract SIM, so a short month and a longer plan come from the same seller type of network.
- Unlimited data is priced at PLN 75 on the Abonament komorkowy plan, which also ranks 59 of 173 brands on that measure.
- Sim only is available, so you can bring your own handset and pay only for the network side.
Cons
- The contract plan runs 24 months, so the unlimited price is tied to a long commitment rather than a rolling monthly deal.
- EU roaming is on fair use terms, which is weaker than plans that include roaming in the monthly price.
- The range runs in Poland, so the plan, support and the prepaid card are aimed at Poland only.
US Mobile
Pros
- Shared data starts at $10 a month on the By the Gig plan, one of the lower entry figures in the listings.
- Unlimited Starter annual comes in at $16.58 a month, below the monthly Unlimited Flex tier for anyone willing to hold a yearly term.
- EU roaming is included across 180 countries, a package only 36.1% of the site listings include.
Cons
- Multi line discount is not offered, although 97.5% of prepaid listings include one, so a family pays full price on every line.
- US Mobile sells as mvno, while Lonestar Cell MTN is network, so readers who prefer to buy from a network operator have fewer like for like sellers to weigh.
- The lowest unlimited rate of $16.58 is tied to the annual term, and contract lengths run 1 and 12 months, so month to month flexibility costs more per month.
Who each suits
T-Mobile Polska
Who it suits
- People living in Poland who want a plan sold by the network itself rather than a reseller, given network and PL.
- Shoppers who want both a prepaid card and a contract option on the same account, since contract and prepaid lists both.
- Households wanting a multi line discount, or travellers who want eSIM and Wi-Fi calling included.
Who should look elsewhere
- Anyone outside PL, where the prepaid card and contract plans do not reach.
- People who want EU roaming included in the monthly price, since fair use applies.
- Readers who need a short rolling commitment, because the contract option runs 24 months.
US Mobile
Who it suits
- Households in the US that want a prepaid line with rollover, so unused data carries over rather than disappearing.
- Travellers from a US base who want roaming included across 180 countries without a separate roaming plan.
- People comfortable running on a host network and managing their own plan, since the seller type is mvno.
Who should look elsewhere
- Readers who want to buy from a network operator rather than a host network, since GETESA at network, Lonestar Cell MTN at network and yesss! at network all sit on the network side.
- Shoppers buying several lines and expecting a multi line discount, because none is offered here.
- Anyone living outside the US, since the plan market is US.

Questions about each
T-Mobile Polska
How much does a T-Mobile Polska plan cost at the cheapest end?+
Plans start at PLN 30 per month on the prepaid card. The reference tariffs add GO! S and GO! M, a smaller and a larger data bundle billed monthly on a short cycle, so entry pricing stays flexible rather than locked. Unlimited data sits higher, at PLN 75 on the Abonament komorkowy plan.
What does unlimited data cost, and how long am I tied in?+
The Abonament komorkowy plan carries unlimited data at PLN 75 per month and runs 24 months. That is the trade-off to weigh: a lower entry price on the prepaid card tariffs, or unlimited data on a long contract. On that measure the brand ranks 59 of 173.
US Mobile
What does the cheapest plan cost?+
The By the Gig plan is the entry plan at $10 a month, with a shared data pool across the lines on the account. Unlimited Starter, the annual tier, is the unlimited option at $16.58 a month, and Unlimited Flex adds a high-speed allowance to the unlimited range on a monthly basis.
What happens to the price after the first year on the unlimited plan?+
The plan contract options run 1 and 12 months, so the annual unlimited tier sits alongside a shorter monthly term. Unlimited Starter is listed at $16.58 a month on the annual term, and the monthly unlimited alternative, Unlimited Flex, is priced higher per month.
