The web page requires you to enter your data card phone number, followed by the SIM number of the 4G card you got from your nearest Reliance Mobile Store and certain other details.
The SIM number is written on the SIM card itself.
The 4G upgrade page also requires you to specify the email ID and contact mobile number registered with the company. If you enter a different mobile number, the upgrade may not work.
The upgrade is part of Reliance’s transition of its network from CDMA technology to 4G LTE as part of its alliance with Reliance Jio.
Voice users on RCom’s CDMA service can get their SIMs swapped starting from May 4.
Meanwhile, RJio is expected to start opening its trial services to the public in coming days. The company is currently ironing out its subscriber activation process as well as doing checks for its network coverage.
