Our verdict on each
PremiumSIM
PremiumSIM suits people in Germany who want a low entry price on a sim only plan, a wide support choice and a fibre option from the same seller. Sim only tariffs start at €6.99, and the fixed line runs on fttc and fttp.
RED by SFR
RED by SFR suits readers in FR who want a sim only plan on 1 month terms with rolling billing and no commitment. Data does not roll over and EU roaming runs on fair use terms, so the low entry price fits light users and short stays rather than heavy data habits.

Pros and cons
PremiumSIM
Pros
- Sim only plans start at €6.99, below the €9.30 median across listed brands
- Terms run 1 and 24, so a rolling option sits next to a longer commitment
- 5G, eSIM and wifi calling are all available, which is what most listed mobile plans carry
Cons
- The fibre line carries a setup fee of €49.99 and post contract pricing of €44.99
- As an mvno, the provider sets its own tariffs on another carrier's network and stays inside DE
- Uploads of 5.8 to 40 Mbps sit below downloads of 1,000 Mbps, which matters for sending large files
RED by SFR
Pros
- Sim only plans, so a new line can be activated on its own without a handset in the same order.
- Billing is rolling on 1 month terms, so a line can end without serving a long fixed period.
- The host network is SFR, and the same provider also sells fixed lines at 2,000 Mbps with routers SFR Box 7, SFR Box 8 option, Box 5G.
Cons
- Data rollover is not offered, so data left at the end of a month expires instead of carrying over.
- EU roaming runs on fair use terms, so frequent travel across Europe is not a flat included allowance.
- Billing is rolling only, while GETESA (prepaid and contract) and Lonestar Cell MTN (contract and prepaid) also list contract billing, so no committed term sits behind a lower monthly figure.
Who each suits
PremiumSIM
Who it suits
- People in Germany who want a sim only plan on 1 and 24 terms
- Households that want mobile and a fibre line from one seller, with €49.99 to budget for at the start
- Travellers who need EU roaming included in 33 countries
Who should look elsewhere
- Anyone after unlimited data, since no unlimited plan appears among the reference plan prices
- Buyers who want the host network itself, where yesss! sells as a network
- People who need service beyond DE, with Lonestar Cell MTN listed as a network
RED by SFR
Who it suits
- Readers in FR who pay as they go and would rather not serve a fixed minimum term
- People who want 5G, an eSIM and hotspot sharing on one bill without a handset
- Households after mobile and fixed lines from one provider, with fibre at 2,000 Mbps and a choice of SFR Box 7, SFR Box 8 option, Box 5G
Who should look elsewhere

- Readers whose address has weak reception on SFR, since yesss! runs on A1 instead

Questions about each
PremiumSIM
What does the cheapest PremiumSIM mobile plan cost?+
The starting price across the range is €6.99, set on a small allnet plan. A second reference plan adds a much larger data allowance at a higher monthly cost, and no unlimited plan appears among the reference plan prices. Heavy data users would pay for the larger tier from the first bill.
How long is the contract?+
Plan contract months run 1 and 24, so a short rolling arrangement sits alongside a longer commitment. Billing is offered as contract or rolling, which lets you match the term to how long you expect to keep the line. Households that expect to move soon should read the longer term carefully.
RED by SFR
What does the entry plan cost and what comes with it?+
The entry plan is priced at €1.99 a month and runs on 1 month terms with rolling billing, and it carries a small data allowance. Larger plans sit above it, all on no commitment terms, with allowances sized for streaming and heavier use. The price list holds the full ladder to compare.
Do I have to sign a minimum term?+
No commitment is attached to any of the plans, and billing is rolling, so the arrangement can be stopped without serving a long fixed period. That is the main difference from brands such as GETESA, where billing covers prepaid and contract, and Lonestar Cell MTN, which lists contract and prepaid.
