If you have already upgraded your Airtel sim card to 4G this information is not for you but if you’re yet to go for your sim upgrade, I just want to share a little information with you based on my own observations while upgrading my sim at Airtel office. I went for my airtel sim upgrade and I noticed that the staff always insist that everyone drops that old 3G sim with them after performing the sim swap. They give you the new 4G sim and collect the 3G sim from the customers, now this seems normal to almost all the customers in the office except me. I wondered what they were going to do with the old sims after collecting them from customers.
Most of the customers don’t even bother to backup and erase their contacts from the sim before handing it over to the staff or anyone doing the upgrade. Most of the Airtel 4G upgrade are done by the roadside vendors are call centers and the sim can fall into the wrong hands. It’s true that the old sim gets deactivated and the new one gets activated but that doesn’t mean you cannot see your contacts if you put the sim in another phone. We should all be security conscious at all time because I know that many people store their BVN and other sensitive information in their sim memory. I’m not saying the Airtel staff are careless or anything like that but the fact remains that they intend to either destroy those sims or recycle them therefore it is important that all your data is COMPLETELY BACKED-UP AND WIPED OFF from the sim card before handing it over to them. No need to place 100% trust in anyone (Staff or not) and say my details are safe with them, play your own role and protect yourself from telling stories that touch. Thanks.
