Youtele started in Surat in 2002. I was one of the earliest customers (I have a 4 digit customer no). Used it till 2015, till the complaints became too much to bear. Then switched over to Reliance Netconnect dongle, which works ok in Surat but is problematic in Delhi. Now waiting for Reliance to upgrade to 4G. Rcom have stopped taking new customers for CDMA as far as I know.
