Tried to unlock my phone using a Sprint sim card

Tried to unlock my phone using a Sprint sim card

I have a samsung note 8 that I was trying to unlock to resell to a friend. I had the unlock code and I went through the instructions and in the instructions it says to use a non-AT&T SIM card. I used my fiancé’s sprint SIM card, put the code in and it said unlock successful. Now that I’m ready to sell the phone to my friend who uses straight talk, she is getting notifications on the phone asking her to configure service by sprint? She says the phone is working but she can’t send picture messages and that notification keeps popping up. Any idea what happened? We tried to rest the phone to get an unlock screen again to put in the code but she said phone didn’t ask for an unlock code again.

The Samsung 8 series of phones will unlock and convert if you let it.  I suspect you interrupted the conversion.  

The MMS problem is no surprise.  She should download a third party messenger like a Textra to resolve the problem. 

Im not sure how to resolve the pop up notice.  Allowing the phone to complete conversion, but that ship sailed when you sold the phone.

I have contact with my friend, is there anything I could manipulate on it to complete the conversion ?
