Hi Steffano,
Thanks for your post and apologies to hear of your circumstances.
We're not able to send a SIM to anything other than a UK address. The SIM will also need to be activated in the UK. Do you have a friend or relative who would be able to collect the SIM from your address, activate it for you and then send on to your address abroad?
The only thing with doing this is that as soon as the new SIM becomes active, your existing SIM will stop working.
Pop back and let us know how you would like to proceed.
Thanks,
