Bharti Airtel has launched its 4G services in 296 towns across India. In order to use this 4G network it is a prerequisite for Airtel subscribers to change their existing 3G sim cards with an upgraded 4G compatible Sim. The 4G smart sim by airtel comes as a kit with a Nano sim along with two adapters for making it compatible with Micro and Mini sim based smartphones. The sim kit bares the tagline ‘Closer to nature, less plastic more green’.
The 4G USIM is provided by Airtel free of cost in its galleries in 4G towns and also provides free shipping if ordered online. Once the subscriber receives the upgraded sim he needs to SMS the 20 digit sim number from his existing connection and send it to 121. Airtel will then send a confirmation SMS to which the subscriber needs to reply with 1. In some time the existing sim will get disconnected from network and the subscriber can then insert the new 4G USIM and resume services.
The process of sim swap is common for both Prepaid and postpaid subscribers. The sim is backward compatible to 3G and 2G networks in regions which are not covered by Airtel 4G. Airtel currently offers 4G at 3G rates, where a subscriber with a 4G compatible handset and sim will get 4G services on his existing 3G voucher. Airtel also offers double data benefit for two months for customers buying a new Huawei Honor smartphone from flipkart.
