GSM/UMTS gateway is unable to register to my 3G network
Please Note ITRS does not provide direct support for GSM/SMS issues, this information is supplied as guidance ONLY.
Currently we have three models of SMS gateways we have tested with our integration:
- Siemens/Cinterion MC55i - the oldest version, GSM, square, with slide-out tray for SIM
- Siemens/Cinterion TC65 - the previous version, GSM, rectangular, with slide-out tray for SIM
- CEP HT910G - the current version, GSM/UMTS (3G) square, with slide-away lid on SIM compartment
