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 ??
