Hi ​@Sonia goldsbury, 

Thank you for reaching out. I can confirm that if you have upgraded your existing iD Mobile contract your number will remain the same.

You can still use your existing SIM as the upgraded plan will be processed on the same SIM card unlike a new plan where you’ll receive a new SIM and new number. 

Thanks, 

Anneline

Took new plan out but I want to keep my number I've had the same number for years came from 02 2 years ago and I took another plan out different prices plan 

You can’t port a number between iD Mobile plans. You’ll need to either return or cancel the new plan and upgrade your existing one or port out the number you want to keep to another network and then port it back.

Got my upgrade from different wibstie u switch 

If it came with a new number you didn’t upgrade; you purchased a new line.
