In Asia markets Multi SIM phones that handles two or three “active” idle modes at the same time have been around for a couple of years. This has forced the market leader Nokia to lauch Dual SIM phones on these markets. The volumes of Dual SIM phones are large and the main driver has been to save money – use the operator that offers lowest call or data rate at the present location and time. For the local Swedish market this device type may have two implications if or when launched:
- The perceived coverage or availability in rural areas using a single personal “phone” can be significantly improved as described in a Wireless@KTH Master Exam Thesis by Eliane Semaan and at the Online Offroad event in co-operation with Skogforsk, SR Kronoberg .
- In addition this type of mobile terminals may be a key driver for small Private GSM networks with and without roaming to other GSM operators.
