Go to the settings of your cellphone then adjust the volume but if ever you already adjusted the sound volume through your cellphone settings and still the sound is low try to contact a cellphone technician maybe there is a problem with your cellphone speaker.

I forgot my phone code,help me a nokia N 80 i


If you lost your Lock Code then Please Connect it to Software dongle (e.g JAF Software Dongle or UFS Software Dongle) using perfect cable of your mobile & then check the boot & then Set your mobile setting as default it will be solved. If your a Mobile Technician then only try this.

If your not A Mobile Technician the Please Visit your nearest Nokia Service Center (Nokia Care) they will do in proper method.

My phone keep asking me to enter restriction code i have also had a technician looked already i payed £15 how do i solve this?


Is the tech did not erase or bypas the previous code? did he use to hook the cp into the computer and use a software to read the IMEI no.

with your problem, the only way is to bring the unit into a cellphone repair center to unlock the code, but you dont have to pay this technician if he did not unlock it, maybe he has no software supported to your phone to bypass code.
