when did you activate your gg sim?

did your phone recognise the gg sim before you activated it?

Reboot the phone and then,


  • Dial *100# to check your top-up credit
  • Dial *100*7# to check your plan

Also read here,


If you dial 43430  it should tell you if the Sim is Active.

Can you call 443? 

I do not work for giffgaff, so cannot check anything on your account. This is a public community - please do not post any personal info.

Most sims are activated in up to 4 hours, but it can take up to 24 hours. 

Please try turning your phone off and back on every 30 mins as this sometimes helps. 


If not once the 24 hours are up and it has still not activated you will need to contact an agent. 

As this is a account related issue you will need to speak to an agent, you can do so by clicking this link of



giffgaff agents will do there best to get back to you within 24 hours but at busy periods it could be slightly longer.

If your request has not had a response within the 24 hours you can click this link below to ask an educator to chase it up for you.

But wherever you do don't resubmit your request to a agent as you'll go right to the back of the que!

Agent's are available from 8am till 10pm
7 days a week  but remember there's less staff on weekends so it could take a little longer for a reply.

Once you've submitted a request to an agent you can

@clairemac88 >>>

Read/Follow the below >>>

⬜ 1, You need to go to ➜

(Ignore if you've already done this bit)

Info you need to know >>>

● The Lost SIM card will be blocked and the mobile etc will / can be IMEI Blacklisted

⬜ 2, Please Note: You'll need to activate the SIM when it arrives (without topping up this time) and also you need to contact a agent to get the security bar taken off,

⬜ Most sims dont need the bar removing. its only when it fails to lift automatically that you have to contact an agent
