How to activate a Vodafone 4G SIM card?

Once you have been issued a new SIM card at the Vodafone store, you will need to activate the SIM by following a simple process.

  • Step 1: You will need to send a text message <SIMEX NEWSIMNO> on toll-free number 55199 (This toll-free number is subject to change and can be found inside the starter kit).
  • Step 2: You will now receive a message from the same toll-free number asking you for the last six digits of your new SIM number to proceed with the verification process. Type the number and press ‘Send’. The SIM update request is processed after 2 hours of sending the message.
  • Step 3: Once your current SIM is disconnected by Vodafone, you can insert the newly issued Vodafone 4G SIM in your 4G handset. In case your handset supports dual SIM functionality and you wish to use multiple SIM cards, it is recommended that you insert your Vodafone SIM card in slot 1 for better speed and performance.

*Do not confuse SIM number with your mobile number. The SIM number can be found on the new 4G SIM card that has been issued. You may also want to take a backup of all your SIM contacts to your phone as it will erase all your SIM data post upgradation for a smoother process. Alternatively, you can back up your phone contacts to a Google account. Your current SIM card will lose its network in a few minutes of making a request.
