Pros and cons
BASE
Pros
- Entry pricing starts at €15 a month on the entry tier, with the tiers above it offering more data on the same contract terms.
- Unused data rolls into the following month, so a quiet month is not simply lost.
- EU roaming is included on the plans, which spares travellers a separate roaming deal.
Cons
- Support runs through help centre only, so anyone who wants a phone line or live chat has to look at another brand.
- BASE operates in Belgium alone, so the plans are of little use to anyone who needs a line in a second country.
- Reference plan prices cover contract tiers only, so anyone after a rolling monthly line has to weigh yesss!, which bills contract, rolling and prepaid.
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.
Who each suits
BASE
Who it suits
- Readers in BE who want the network and the plan from one company, with billing under contract and prepaid.
- People who travel in the EU, since roaming is included on the plans.
- Data heavy users who want headroom and can step up the tiers on the same contract structure.
Who should look elsewhere
- Readers shopping purely on the opening figure, since Lonestar Cell MTN lists $0.20 against €15 at BASE.
- Anyone after a rolling monthly option, because BASE bills contract and prepaid only, while yesss! bills contract, rolling and prepaid.
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.

Questions about each
BASE
How much does BASE cost to start, and what do the reference plans include?+
The entry tier sets the starting price at €15 a month, and the tiers above it each carry progressively larger data bundles. These are recurring monthly contract prices rather than a limited introductory offer, so the figure that applies is the one attached to the tier you pick.
Can I get a BASE plan without a contract?+
Billing under contract and prepaid covers both contract and prepaid, so a contract is not the only way in. The published reference tiers are all sold on contract, which makes prepaid the option to ask about if you want a shorter commitment. SIM only service runs on the same network.
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.
