Question: Dual sim
I have an IPhone 5s with Tmobile USA and an iPhone 8 with EE UK. The IPhone 8 is unlocked. The 5s is used very infrequently, however calls do come and unexpectedly so I always carry both phones. The 5s is dying has to be charged daily.
Rather than buying a new phone to replace the 5s I’m considering a Dual Sim adapter from Simone.com an outfit based in Switzerland
Has anybody used one of these adaptors with an iPhone? And was it successfu?
