Our verdict on each
BASE
BASE is a network operator selling its own contract and prepaid plans in Belgium, which suits anyone who wants mobile service straight from the company running the network. Entry pricing starts at €15 a month on the entry tier, with eSIM, 5G and wifi calling part of the package.
MasMovil

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.
MasMovil
Pros
- Entry price of €4.90 sits below the site median of €9.30, and it ranks 87 of 258 brands on that measure.
- Plan terms run 1 month, so there is nothing to serve out before you leave.
- Sim only tariffs are available, and eSIM is offered, so you can bring a light line without a handset.
Cons
- Data rollover is not available, so unused data is lost at the end of each cycle.
- Lonestar Cell MTN lists an entry price of $0.20, lower than €4.90, so the cheapest way in sits with that brand instead.
- Roaming in the EU runs on fair use terms rather than being included outright.
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.
MasMovil
Who it suits
- Readers in the market listed as ES who want a single-market setup.
- People who want a SIM only line and a term of 1 month with no long commitment.
- Anyone who needs hotspot sharing and 5G on a budget line.
Who should look elsewhere
- Anyone who relies on rolling monthly billing, since yesss lists contract, rolling and prepaid options.
- Readers who call often from indoors on weak signal, since wifi calling is not supported.
- People who want unused data to move into the next cycle, since data rollover is not available.

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.
MasMovil
How much does a MasMovil line cost to start?+
Lines start at €4.90, which is below the site median entry price of €9.30. Across the site, €6.99 is the typical starting figure for this kind of deal, and €6.99 is the typical figure among mobile networks.
Do I have to sign a long contract?+
Plan terms run 1 month, so there is no long minimum to serve. That is a good match for anyone who expects their data use or income to change and wants to leave without a large exit bill.
