Will the 2nd sim slot of my dual sim phone be useless if Rogers shuts down its GSM (2G) network in 2018?
Based on wikipedia, Rogers is going to shut down its GSM (2G) network in 2018. As Fido is Roger's subsidiary and they share the same GSM (2G) networks, does that mean that Fido will also shut down its GSM (2G) network that would render many "older" dual sim phones to have only one sim slot functional?
Another question is that the Speakout website says its sim is compatible with most unlocked 3G/HSPA+ handsets with frequency bands of 850/1900MHz, which means that it runs at 3G? Why does my phone goes to automatically go to 2G when Speakout's sim is for 3G?
Any suggestions for a dual 4G/3G phone, i.e., when one sim is at 4G, the other sim will be at 3G, if Fido may also shut down its GSM (2G) network?
