Sprint Unlock Issue – IMEI and MEID Not Matched

I’m not sure if this could be the cause of some Sprint unlock problems, but thought I would put it out there. FYI, my phone is unlocked, S-Off, SuperCID.

I have a Sprint One M7 that had a bad IMEI. I repaired IMEI and did the Sprint unlock which said it was successful, changed to GSM network setting but still got Invalid SIM card. I was double checking things and noticed that the IMEI was correctly changed but the MEID remained the same (old number). I know that on Samsung phones for Sprint Domestic unlock IMEI and MEID have to match in order to get a signal on GSM networks. Could this be the reason some are having problems?
