I would like to be able to ring my friend in Gibraltar, i am in england. What is the best sim card for me to be able to ring him? What is the cost of calls? Many thanks

Just returned from a Med. Cruise.   Noticed problems with data connections in Turkey, at two different ports.  Changing to 3G solved the problem.   Other than that, the card worked well on data.  

I initially bought a global sim with the 07430 number years ago. After the service changed to use the IOM/Jersey number, the sim got migrated to the UK simple calling plus service. I didn't bother ordering a replacement global SIM because I did not have plans to travel outside the UK.

Anyway, my question is, can I port my UK simple calling plus service 07430 number to another UK mobile network?

Thanks.

Travelling to France in May and would like to get the French mobile umber before I go, is this possible
by registering with your International SIM?

I want to buy a sim where my inidian friends can text me at the local Indian rate, and I receive free within my contract

I bought a SIM 3 years ago; when it arrived here in the US, I put it in my phone to check it.  When I got to the UK, it would not work there. I want to be sure that this SIM I just received will not do the same. I was told I could put it in my phone here and check it, and even though it would pick up a server here, it would still shift to a server in the UK when I get there in February.  Is that accurate?  I don't want to insert the SIM and lose the money I've spent for it this time, too.  Thanks for your help.
