Our verdict on each
Blau.de
Blau suits anyone who wants a cheap German mobile line on a handset they already own, with sim only plans starting at €6.99 a month and no credit check. The trade-off is term length: only Blau Allnet S Flex rolls, and no plan in the range is unlimited.
Simpel
Simpel is a Dutch virtual network operator for people who want a cheap sim only plan, a 5G connection and an eSIM without a credit check, with tariffs starting at €2.50 a month. The catch is commitment: plans run on 12 and 24, and data rollover is not on the menu.

Pros and cons
Blau.de
Pros
- Entry is low for a contract mobile plan: Blau Allnet S Flex starts at €6.99 a month, under the €9.30 entry price across the site.
- No credit check is required, so a signup does not hinge on a credit file.
- An esim is available, so a compatible phone can be provisioned digitally on the host network.
Cons
- Use inside the EU is on fair use terms rather than a stated allowance, so a month of heavy use in Europe can cost extra.
- Blau serves DE, so the deal does not stretch to a second market.
- Terms run 1 and 24 months, and the roomier plans, Blau Allnet M and Blau Allnet XL Promo, sit at the long end, while only Blau Allnet S Flex rolls.
Simpel
Pros
- A credit check is not required, so an application does not rest on a credit file.
- An eSIM and 5G are both offered, so a recent handset works without waiting for a card in the post.
- EU roaming is included in the sim only line, and only 36.1% of the listings include it.
Cons
- Data rollover is not offered, so unused data from a quiet month is lost rather than carried into the next one.
- Plans run 12 and 24 with billing on contract, and leaving early is governed by After minimum term rolling monthly with 1 month notice, while only 78% of the listings are month to month.
- Support runs on email, help centre and community, with no phone line listed, while 81.5% of the brands offer one.
Who each suits
Blau.de
Who it suits
- Households that already own a handset and want an extra line, since every Blau plan is sim only and a multi line discount applies.
- Anyone who wants to sign up without a credit check, since none is required, and who can pick contract, rolling or prepaid billing from contract, rolling and prepaid.
- Light-to-moderate data users who travel now and then: roaming reaches from 100 countries, with EU use on fair use terms.
Who should look elsewhere
- Shoppers who want to buy straight from the host network: Blau is a seller of type mvno, while GETESA, Lonestar Cell MTN and yesss! each sell as a network.
- Anyone who needs unlimited data, since no Blau plan is unlimited; yesss! sets its own tariff as a network seller.
- Users outside DE, where the range is sold in a single market, so a network from their own home market such as GETESA or Lonestar Cell MTN is the fairer starting point.
Simpel
Who it suits
- People in NL who bring their own handset and want sim only service on 5G with no credit check.
- Households that want both lines in one place, since fibre runs to 1,000 Mbps and hardware is Modem included.
- Travellers who would rather not buy a roaming pack, since EU roaming is included.
Who should look elsewhere
- People set on a network operator rather than a virtual one: Simpel is an mvno, while GETESA (network) and yesss! (network) sit on the other side of the market.
- Anyone unwilling to sit a full term: plans run 12 and 24 with notice set by After minimum term rolling monthly with 1 month notice, so if your plans may change, read the terms at Lonestar Cell MTN (network) as well.

Questions about each
Blau.de
How much is the cheapest Blau plan?+
Blau Allnet S Flex is the entry plan at €6.99 a month, billed rolling with a month's notice rather than a fixed term. The next tier, Blau Allnet M, carries a longer commitment, and the largest listed, Blau Allnet XL Promo, sits at the long end of the term range. Among the brands ranked on entry price, Blau holds position 132 of 258.
Does Blau run a credit check?+
No credit check is required, which is why these tariffs sit alongside the no credit check plans in this group. Billing spans contract, rolling and prepaid, so the same walk-through applies whether a customer picks a fixed term or a prepaid option, and an esim is available to get the line running without a paper card.
Simpel
How much does a Simpel sim only plan cost to start?+
Sim only plans start at €2.50 a month, below the €9.30 median across the brands tracked here. The lowest priced bundle with a larger data allowance runs on a year contract, and unlimited calls come as a small monthly add-on rather than a plan of their own. Read the tariff terms, since the entry price is separate from what you pay later.
How long is the contract and can I leave early?+
Plans run 12 and 24 with billing on contract, and the notice terms are After minimum term rolling monthly with 1 month notice. Only 78% of the listings are month to month, so a shorter rhythm does exist elsewhere in the market. Read that notice wording before you sign, because rolling monthly is not the same as having no term.
