Pros and cons
1pMobile
Pros
- Plans start at £5 a month, and billing runs rolling and prepaid with terms of 1 and 12 months, so a reader can start small.
- No credit check is required and an eSIM is available, which means a new number can be live without a handset.
- 5G, WiFi calling and hotspot sharing are all included, and a multi line discount applies to households.
Cons
- EU roaming is fair use rather than included, and roaming overall reaches 46 countries.
- Terms run 1 and 12 months, so the rolling option is the pick for anyone who might move, and the annual plan only makes sense for readers already settled.
- 1pMobile is an mvno, while GETESA, Lonestar Cell MTN and yesss! all sell as network providers, so a reader who wants the operator itself is looking at a different kind of seller.
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.
Who each suits
1pMobile
Who it suits
- Adults in the UK who want a Sim only line at the cheap end of the price range and can set up an eSIM themselves.
- Households adding a second line, where a multi line discount applies.
- Readers who want a rolling monthly line they can end quickly, with no credit check at signup.
Who should look elsewhere
- Anyone who wants to buy from the network operator rather than an mvno: GETESA and yesss! sell as network and network providers.
- Heavy data users on a tight budget, since the unlimited plan costs £25 a month, with the network sellers GETESA, yesss! and Lonestar Cell MTN the ones to price against.
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.

Questions about each
1pMobile
What does 1pMobile cost to join?+
Plans start at £5 a month, and that figure belongs to the smallest data allowance in the range. A heavy user should budget on the unlimited plan rather than the entry number. The entry figure is a month to month spend, not an introductory deal that resets later.
How much is the unlimited data plan?+
The Unlimited plan is listed at £25 a month. It is the price to hold in mind for anyone who regularly uses more data than a capped allowance allows, and it is the figure that pushes 1pMobile further back in our price comparison than its entry plan does. Readers who stay well inside a small allowance pay far less.
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.
