It works for my Galaxy S5 Perfectly! And totally free!
Why is an Estonian +372 SIM card mandatory? I would pay for this app if this unnecessary restriction were removed. I can't use it as I don't have a +372 SIM. Why this restriction?
Excellent Nice app.....
Good. Great, actually, but the icon is always there in the status bar.
Mike Tried with my Travelsim. Works in the background!
