mobil phones

Hi All

Good Evening to you .

At the moment we have two mobil phones from BT spain ,

We wish to change them for various reasons

We use one of the phones to Call and recieve calls from the UK . the other is for more use here in Spain

Can anybody point us in the right direction re costs each month / customer service/ english speaking(although we do speak Spanish) and overall reliability . We also want to keep the same numbers

Most Urgent as our contract runs out end of the month. Sorry to be a pain any help most gratefull

Most Kind in advance

Regards
