Our verdict on each
sim.de
sim.de suits people in Germany who want a cheap sim only line with a monthly option and a fixed contract choice on the same tariff sheet. It runs on the 1&1 network, and its entry price of €6.99 sits well under the market median for entry pricing.
Twigby Mobile
Twigby Mobile suits US customers who want a sim only line with no contract and eSIM support, and the price on entry is one of the sharper ones on the site. The catch is what happens after the introductory period, when renewal rates sit well above $5.

Pros and cons
sim.de
Pros
- Entry pricing of €6.99 is below the site median of €9.30
- The Unlimited on demand plan costs €19.99, under the site median unlimited price of €23.19
- Contract terms run 1 and 24, so a plan can sit on a monthly term or a longer one
Cons
- The Unlimited on demand plan is tied to the longer of 1 and 24, so unlimited data is not offered on a monthly term
- Service runs in DE only, so the tariffs are not offered outside that market
- As an mvno, sim.de sells on the 1&1 network rather than owning it, unlike the network operators getesa, yesss! and Lonestar Cell MTN
Twigby Mobile
Pros
- Entry pricing of $5 sits comfortably in the lower end of the plans we price up.
- Billing is rolling and plan contract length is 1 month, so there is no long tie-in.
- Sim only, eSIM, 5G, wifi calling and hotspot sharing are all included.
Cons
- Renewal pricing on the entry plans is well above the $5 headline once the introductory period ends.
- Support runs on chat and help centre, so there is no phone line for problems that need a voice.
- The unlimited plan costs $25, a large step up from the entry figure of $5.

Questions about each
sim.de
How much does a sim.de sim only plan cost to start with?+
The cheapest way in is the entry data plan at €6.99 per month, and it can run on a monthly term rather than a long contract. The larger data plan and the Unlimited on demand plan sit on the longer of 1 and 24 instead.
How much is unlimited data on sim.de?+
The Unlimited on demand plan costs €19.99 per month, and it is tied to the longer of the contract options, 1 and 24. That price sits under the site median unlimited price of €23.19, but the commitment is the part to weigh.
Twigby Mobile
How much does Twigby Mobile cost to start?+
Plans start at $5 on a rolling monthly basis, with a plan contract length of 1 month. That headline figure is introductory, so the standard rate is higher once the first period ends. Budget on the standard rate rather than the opening price.
What does unlimited data cost?+
The unlimited plan is priced at $25. That is well above the $5 entry figure, so unlimited data is a step up rather than a default. Billing stays rolling, so nothing locks you in beyond the rolling month.
