Pros and cons
MobileX
Pros
- Build Your Own starts at $3.88 on a plan where the data allowance is set by the customer
- Plans run 1 month, so there is no long term to serve
- Unlimited talk and text plans start at $14.88
Cons
- European roaming is paid, so travel adds cost rather than arriving with the plan
- The seller type is mvno, so service runs over a host network and local coverage needs checking
- Coverage is listed for US, so anyone who needs service across several countries should look wider
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.
Who each suits
MobileX
Who it suits
- Residents of US who want a prepaid plan with no long contract
- People who want unlimited talk and text from $14.88
- Readers who want an eSIM, rollover data and hotspot sharing on a flexible plan
Who should look elsewhere
- GETESA readers who would rather buy from a network than a mvno
- Lonestar Cell MTN readers who want the network itself rather than a virtual brand
- Travellers who need roaming inside the monthly plan, since European roaming is paid
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.

Questions about each
MobileX
What is the cheapest MobileX plan?+
Build Your Own starts at $3.88 and you set the data allowance on it yourself. The published reference prices for the plans are monthly and month to month, so that entry figure is the ongoing figure rather than a promotional rate that changes later. A reader comparing a low headline price with a long contract deal is comparing two different structures here, not two stages of one sale.
Does MobileX use contracts or lock-ins?+
No long term is attached. Billing is prepaid and rolling and plans sit at 1 month, the short contract length that flexible mobile deals tend to use. Nothing ties you in for a year, so a reader who wants to change plan or walk away can do so without serving out a term first.
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.
