Needs to have both Sims active to receive & make calls
Ability to selectively switch off one sim desirable
Must be stable.
Android preferred but needn't be latest ver unless I am really missing something?
Do these things keep sms messages discrete for each sim or do they merge them into a common "in box"?
Is there any alternative? Seen adaptors that claim to mount 2 Sims in one phone but they seem to have failings in what I want? Unless someone knows better? Cheers Jim K
