hi guys, please i don't know what is wrong with my phone. i bought the phone last year camon cx air i inserted 2 mtn sim in it. The 3g always walking fine, then few months ago i discovered that when my neighbors mtn sim is having 3g network available mine won't have. it keeps fluctuating so i do have Edge most of the time.
Note: When i inserted airtel sim the 4g and 3g works fine. Also when i use mtn in another location where the network is blazing it works fine
but
I don't know why my roomie and other neighbors will have mtn 3g available on his phone working perfectly but mine keeps fluctuating everday.
please any help. Thanks
