Somebody here suggested the german-based vistream SIM-Cards.
vistream (powered by Materna) is a virtual network operator using the German e-plus Network.
Prefix is +49-1570-xxxxxxx
vistream Customers report about strange problems with Callback-Roaming in various foreign countries. It may work, but it may not work, too. German speaking/understanding readers could have a look at www.telefon-treff.de for more details.
vistream uses a Dual IMSI SIM-Card with SAT-Callback, which is a little bit more sophisticated than the known SIM-cards from IoM, UM or other Companies. So should have a newer SAT-compatible phone (like Nokia 6310i or later) |
Well callkey will be back, that is what the expert here on the forum says. So don't say there gone they will be back
The same expert attacked me saying I said dual sim was a home brew solutions (I used other words) It's funny that I read now that there are indeed problems with these dual sim card. But agian there is 1 expert here that knows everything so don't speak bad
