Well there is light on the horizon. I had the exact same issue and wasn’t getting anywhere. In a last ditched attempt to get my mobile data plan working I emailed the EE contact I had spoken with when I called about my SIM card delivery. He called me back immediately. After explaining my frustration he put me through to someone in the technical department who informed me that the previous advice I was given during 3 calls (primarily pair/unpair) to the technical department was incorrect. He then took some details from me & manually set up the mobile data plan. He said it takes about 4 hours to set up so he arranged to call me back in 4 hours. He called back 3 hours later and everything was set up. 2 minutes later I then had a call from the guy that I originally email to check that I was all sorted.
The guy I originally contacted was David ******* The tech guy was called Geffen. They were both a breath of fresh air after going through the pairing/unpairing scenario so many times in one week. My email was sent at about 5pm last Friday and all was done and dusted by 9pm so it may be better to contact EE in the evening as they seem to be getting high call rates during the day. When you get in touch with EE again please tell them my experience and they may get you the right help. Good Luck
