How To Activate Vodafone SIM Which Is Deactivated?

If you have a Vodafone Pay-as-you-go number, you need to make it active by using at least one activity such as sending a text or making a call every 180 days.

If you don’t use your Vodafone SIM for 3 months (90-days), Vodafone will send a text message that your account will expire and there is no activity for the next 3 months ( 90-days). After the 180 day period, your Vodafone SIM will no longer work.

Furthermore, if your phone is stolen or lost and you did not apply for a replacement SIM for 180 days, your existing SIM will also get disconnected. In that case, you need to get a replacement SIM and activate it through the above-mentioned methods.

To activate a Vodafone SIM that is deactivated, you can not do it yourself online. You have to contact Vodafone to see if your SIM, MSISDN, and IMSI can be re-activated at all. It is because these settings can be assigned to somebody else if you fail to take any action for 180 days.

To reactive your Vodafone SIM:

  • Call Vodafone customer care or visit a Vodafone store
  • Submit the reactivation request
  • Provide valid proof of address and photo ID
  • Wait for the confirmation call to get your number reactivated
