Pros and cons
Kyivstar
Pros
- Kyivstar sells as a network (network), so the SIM only deal comes straight from the operator rather than a reseller.
- Contract length is 1 month, a short commitment next to a long fixed contract.
- An unlimited option exists in SuperGig Light eSIM, prepaid at UAH 400 for anyone tired of counting data.
Cons
- European roaming runs on fair use terms, so frequent travel is not covered outright.
- Plans run in UA only, so readers based in another market would be looking at the wrong operator.
- Billing is limited to contract and prepaid, with no rolling monthly option for people who like to cancel freely.
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
Kyivstar
Who it suits
- People living in UA who want the network's own SIM only line with eSIM support.
- Buyers happy to cap their data and pay less, since entry pricing starts at UAH 220 on a contract plan.
- Customers who like several routes to help, offered through chat, phone and help centre.
Who should look elsewhere
- yesss!, if you want a rolling billing option, since yesss! lists contract, rolling and prepaid while Kyivstar bills on contract and prepaid terms.
- Lonestar Cell MTN, if the entry figure decides it, since its entry price is $0.20 against Kyivstar's UAH 220.
- GETESA, if you want a second prepaid and contract pair to weigh, since GETESA lists prepaid and contract while Kyivstar serves UA only.
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
Kyivstar
What does the entry plan cost?+
The entry plan is VSE RAZOM Comfort at UAH 220, sold on a contract basis. The range also lists VSE RAZOM Legkyi Contract as a larger contract plan. Because Kyivstar is a network seller rather than a reseller, these are the operator's own tariffs, so the figure quoted is the network's own.
Is there a plan with unlimited data?+
Yes. SuperGig Light eSIM is a prepaid plan priced at UAH 400 with unlimited data, and it is the only unlimited option listed. The other two plans, VSE RAZOM Comfort and VSE RAZOM Legkyi Contract, come with a data allowance instead, which is where the lower UAH 220 entry point sits.
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.
