Our verdict on each
1&1 (1und1)
1und1 is a German mobile carrier, not a travel eSIM, so it suits readers who live in Germany and want a home plan that still works abroad. Its flat rate adds unlimited data, subject to a fair use policy, plus 5G and instant activation, and roaming spans 33 countries from €9.99.
bmobile Solomon Islands
Bmobile SI Limited identifies the Solomon Islands operator and names four operating provinces. Its data page directs subscribers to dial *888# to choose a bundle and lists daily-validity options; the indexed capture is months old.

Pros and cons
1&1 (1und1)
Pros
- Unlimited data, 5G and instant activation sit in one flat rate from €9.99, and the fair use policy says what happens after the high-speed volume is used up.
- Support runs on email, chat and phone, so help comes from the carrier itself.
- Top-ups are available, and regional reach suits a short trip away from Germany.
Cons
- Roaming spans 33 countries, well short of Zwitchy at 200.
- The fair use policy requires an ordinary residence in Germany, so the roaming offer does not suit visitors without a German home.
- The €9.99 price sits above the site median of €5, and it is a carrier home plan rather than a travel eSIM.
bmobile Solomon Islands

- The provider identifies its Solomon Islands operation and four provinces.
- Subscribers can use *888# to choose from the listed bundle options.

Questions about each
1&1 (1und1)
How much does a 1und1 roaming plan cost?+
Plans start at €9.99, and that price buys the home contract rather than a travel pass. The site median price across the brands listed is €5, so a reader comparing on price alone will find eSIMGo.is cheaper at $0.99.
How many countries does 1und1 roaming cover?+
Roaming spans 33 countries, which is far fewer than Zwitchy at 200. The plan is regional in scope, so a trip to a handful of nearby countries is the realistic use rather than a world tour.
Is the data allowance really unlimited?+
Unlimited data is included, but a fair use policy applies: use has to show an ordinary residence in Germany, and once the plan's high-speed volume is used up data continues at a much lower speed. The EU allowance on Unlimited XL runs monthly, and a per-GB charge follows it.
How fast is the connection abroad?+
5G is part of the plan, and at home traffic runs on 1&1 Mobilfunknetz (Open RAN) and Telefonica Germany (national roaming). Speed abroad depends on the visited network, while the fair use policy requires ordinary residence in Germany and applies roaming surcharges when it is not met.
