I also got the 750 plan, plus offered an upgrade on 12/12/10 to have my text go from a half minute to a full minute. I called Net10 which a woman had me enter five codes and then try a local text, still charged me full minute. She then had me enter three more codes turn off phone for five second and then turn it back on and not to use it for an hour as she would be doing upgrade. Also she reimbursed me the five minutes I was charged for texts up to that point. Well much later that night I did a text to my sister in law in Oh. I was still charged a full minute, I tried calling that night to find out they were closed, so I had to wait the next morning. So the next morning I called again and was told to enter another five codes and to try a local text, again still being charged a full minute! The man tells me to hold while he talks to a supervisor after being on the phone for like two minutes and said he is still discussing the situation with his supervisor and they maybe sending me another phone, would I please hold for another couple of minutes. We he comes back on the phone he then informs me I have to buy a new phone!! Why should I have to buy a new phone with something that happened when I got their minutes and upgrade. My sister in law in Oh. just got the 750 minutes this morning to also have her phone charging her a full minute for text, this definitely sounds like a problem with Net10, not my phone. I was told my phone was no longer compatible! Plus this man didn't even reimburse me the minutes that was used, said he would only do that if I buy a new phone! Well when I buy a new phone it will definitely be through another carrier, even though I never had a problem with Net10 before and really enjoyed their service, this has now ruined my confidence in them.
