Our verdict on each
Kyivstar
Kyivstar suits anyone in Ukraine who wants a network's own SIM only deal with a short contract and the option of an unlimited eSIM plan. Entry pricing starts at UAH 220, and the trust side rests on a long operating history plus support you can reach several ways.
US Mobile
US Mobile suits US households that want a prepaid shared data plan or an annual unlimited tier, and it scores 9.1 overall for price and offer. The trade-off is the annual term behind the cheapest unlimited rate and a missing multi line discount for families buying more than one line.

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.
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
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.
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
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.
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.
