I bought a new pay monthly phone with sim plan, but I am currently Three mobile customer. How can I keep my currently number with new sim card?Should I switch my Three number to IDMobile first? and then active new IDMobile sim card and merge with old number? Thanks in advance!

Okay @rogercccc, ask Three UK for a PAC.Then give this PAC (for the number you want to keep) to iD Mobile to use with your iD account and SIM.This community article should help.

@niasirow Welcome to the community you can log into the IDMobile Live Chat. Once you've done so in the message box type in "To speak to someone" An agent will get back to you and hopefully sort matters out with you.Joe
