I'm from Reliance Kolkata CDMA Circle. CDMA service stopped on 24th May .. Now I've one ages old Reliance CDMA phone [ Nokia 2112 ] - 10 years and still kicking 
It has In built / Non removable SIM card or It's a Operator locked phone. Anyway, you can't put a sim card into this phone. Now I'm not getting any CDMA signal and I want to migrate to reliance 4G. So how am I suppose to keep my number and migrate to 4g ? Because as per Reliance website you need to SMS the 4G sims serial number from your existing CDMA phone :
Reliance Communications | 4
but if I don't get network coverage on CDMA phone how am I suppose to send the SMS for migration or even contact reliance CC ?
Anyone have any clue ??

Reliance Mobile Prepaid
Recharge your existing CDMA connection with the 4G upgrade recharge. To know the upgrade recharge value please click here .
After recharging, from your existing CDMA SIM, SMS 4G < space > 19 digit SIM number of the new 4G SIM to 1299.
Alternatively, you can also call on 1299 from your CDMA mobile and enter your new 19-digit 4G SIM number. You will get a confirmation SMS about your 4G SIM upgrade.
