I have a CDMA phone in Vadodara. I was offered an add-on GSM connection on this number, with 1 year free access between the 2 numbers. My wife is using the GSM number.The GSM connection has NO NETWORK in our house which is on one of the main streets in the city!! When we went to Uttar Pradesh a while back, even in a place like Lucknow, there was no network in our guest house! All over Uttarakhand, there was no GSM network though the CDMA phone worked.
Funny thing is, while there is NO NETWORK COVERAGE on the GSM phone when we want to call someone from our house in Vadodara, the coverage miraculously appears when Reliance want to send their marketing messages to this number!
When we called the toll-free number to register on the Do no call service, there was a lengthy message about how to register for this service via SMS; when we punched the digits to talk to a Customer Service Rep, the service said they were all busy and disconnected us within seconds!!
Dont go for this service until coverage improves!!
