Things from me about me …

SimQuadrat offers own mobile numbers and supports SMS in Roaming.


I have tested a new product by SipGate called SimQuadrat for about 4 months so far. The service was initially launched as a mobile phone service with a geographic german phone number. Recently SimQuadrat added the possibility to add a mobile number for free. The system even allows to select from a few numbers during the subscription process.

As SMS transmission didn’t work in Roaming (tested in Luxembourg), I was curious and tested SMS transmission using my new mobile number. The SMS to a LuxGSM number arrived within a minute. I retested the transmission using my geographic number on the SIM card, delivery to LuxGSM worked fine as well. Unfortunately LuxGSM can only reach SimQuadrat mobile number via SMS, the geographic number are unreachable by SMS from LuxGSM.
