The Mobal World Phone service you currently have has been discontinued for new/replacement orders. We are therefore unable to transfer your number to a new SIM card.
If you wish to keep your existing service and phone number you will need to keep using your existing SIM card. It may be possible to cut your SIM card to size using a suitable SIM cutting tool. Alternatively, a local cellphone store may offer this service for a small fee.
Please note SIM resizing can damage the SIM card beyond repair. In this event you would need to purchase a new SIM card – which would be assigned a new UK cellphone number. You can order a new SIM card at: www.mobal.com/international-gsm-sim-card/
Alternatively, for trips to Europe (particularly if you require cellular data) you can consider our Europe Plus plan: www.mobal.com/europe-sim-card/
