I use an Android mobile phone with 2 sim cards. I adjust the first sim to show its phone number, and the sconde should hide. The problem is, either it shows the mobile number of both sim cards after a short time or it hides. The adjustments always gets messed up. So after I correct the adjustment of one of the sim cards, the adjustment of the other sim card also changes to the same hiding or showing adjustment of the just corrected. Is this problem solved at Firefox OS? You are welcome to write me, if you need more detail about this question to [email protected] Kind regards
