Hello, I have my phone bv7000pro from one week, is arrived with installed android 6, I tried my 2 sims , one voice+data and another only data, and when I tried to use the sim only data, tethering didn't work, but the sim with voice+data function well with the data.
I have tried some solution like change the position of the sims, switch off the voice sim and so on...but nothing happen, the only solution was to insert only the data sim.
I have searched the solution on the forum, and I have seen the new ROM with "android 7", I have updated the phone with new ROM, and the problem with the tethering with 2 sims was solved, I was very happy, but after less time android 7 said me through OTA that was available a new update (154mb) , I made the new update, but after this update the problem with the 2 sims mysteriously is returned the same.
I have tried the "recovery factory reset" but nothing happen.
Do you have any suggestion???
Thanks in advance
