How to activate an Idea 4G SIM card?

Once you have been issued a new SIM card at the Idea store, you will need to activate the SIM by following an easy process. You simply need to send a text message <SIM simno> to 12345 and reply with ‘Y’ to a confirmation message.

*Do not confuse your 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 backup all your contacts before you follow the process. Your current SIM card will lose its network in a few minutes of making an upgrade request.

Once your current SIM is disconnected by Idea, you can insert the newly issued Idea 4G SIM in your 4G handset. In case your handset supports dual SIM functionality and you wish to use multiple sims, then it is recommended that you insert your Idea SIM card in slot 1 for better speed and performance.
