Why would the mobile be cut off ??
Why not top your mobile up with say £20 worth of credit ONLY for emergency calls back home and buy a phone card out in
Icmeler to make longer calls back home, that way people can contact you without it costing you a fortune ??
We bought the cards and they're dirt cheap - 5 lira for 50 mins of calls to UK land lines, or 10 lira for 100mins worth of calls.
We used hubbies vodafone last year (he'd had passport put on his phone to used it abroad) and were told it was 75p to connect and free from his inclusive minutes there after. This was fine in
Greece but it didn't apply in Turkey (this they forgot to tell us

) and we got stung with a phone bill over £200
