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.
MobileX
MobileX suits US readers who want a prepaid plan with a low entry price and no contract attached, scoring 9.4 overall. Build Your Own starts at $3.88 on 1 month, and that same monthly rate carries into every later period, so nothing has to be unwound at renewal.

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.
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
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.
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

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.
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.
