Pros and cons

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.
  • BASE sells as a network, so the network and the bill come from the same company, and eSIM and wifi calling are both available.

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.

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.

Core features

SIM only plans are available from BASE, and the network runs 5G. An eSIM is offered, so a line can be set up without a physical card, and wifi calling carries calls over a wifi connection indoors. Data rollover is included, so data left unused in a month moves into the next rather than expiring on the billing date.

The company behind it

BASE sits under Telenet Group NV, is headquartered in Belgium and has been trading since 1999. Customer support runs through help centre, so most questions are answered through written self service guidance rather than on a call or in a live chat window.

Frequently asked questions

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.

What does roaming cost on a BASE plan?+

Roaming across the EU is included on these plans, so using the phone abroad in the EU does not arrive as a separate charge on top of the monthly price. Not every seller treats it that way: in the listed mobile networks, 38.5% bill EU travel separately.

Does BASE support eSIM, and can I take a SIM only plan?+

Yes to both. An eSIM is offered, so a line can be activated on a compatible handset without a physical card, and wifi calling is supported for calls in places with poor reception. SIM only plans start at €15 a month on the entry tier, and the network runs 5G.

Where does BASE run, and does the service work outside that market?+

BASE operates in Belgium, and the plans are sold for use there. For anyone who needs a line that works across several countries, a single market network is a narrow choice, and roaming terms become the deciding factor. EU travel is covered at included, which covers the EU rather than destinations beyond it.

How do I get help from BASE?+

Support runs through help centre. That means written self service guidance is the route to an answer, rather than a phone line or a live chat window. If you want to talk a problem through with a person, factor that into your choice before you sign up for a contract tier.

Is BASE a network operator or a reseller?+

BASE sells as a network, so the network and the plans come from the same company, which is part of Telenet Group NV. The service is offered in Belgium, and the company has been trading since 1999, so the plan sits with the business that runs the infrastructure.

What happens to data I do not use?+

Data rollover is included, so anything you do not use in a month carries into the next instead of expiring. The contract allowances sit on fixed tiers starting at €15 a month, and rollover keeps whatever you leave unused available in the following period.

Who should pick BASE over the alternatives?+

BASE fits readers who want the network and the plan from one company, EU roaming at included, and both contract and prepaid billing under contract and prepaid. Look elsewhere if the opening price decides it: Lonestar Cell MTN lists $0.20, and yesss! bills contract, rolling and prepaid.
