Want to keep my phone number after my contract expires

[nodsknockers]

My phone contract ends in January. I moved to Vietnam in September so will not be renewing, as I now have a Viet Sim. However, I plan to return to England in the Summer and would like my old phone number when I return. Can anybody suggest the most cost-effective way of keeping my old number? Thanks

@nodsknockers : Call CS to cancel with 30 days notice & ask for it to be moved to PAYG.

To save the SIM going into hibernation due to lack of use, just remember within every 179 days (~ 6 months) to make a chargeable action like making a chargeable call or text, topping up or buying a Pack or Add-on, not just using your mins, texts or data from any Pack or Add-on you might have.

Just make sure that, after migrating to PAYG, you use the (what will be a) new PAYG SIM in the UK first before travelling abroad.

This is how roaming is enabled which unlocks the ability to use your phone on foreign networks.
