I bought the N7105 from Phones4U and unlocked it to use when my SGS3 LTE was playing up but since moved my 3 SIM into the phone. It was working flawlessly for about a month but then started, maybe once per week or once every second week, getting fixed in a state where it seems to think that there's no mobile signal. Fair enough, sometimes I lose signal, however when the signal comes back the phone remains stuck in this condition. HSPA+ data is working, it shows the correct network name and can receive incoming calls but the "no entry" icon is in the notification bar and when I try to make an outgoing call I'm prevented from doing so with an error message indicated "The selected mobile network is not available". Disabling the data connection, searching for networks and toggling airplane mode don't seem to help and I can only make outgoing calls again by doing at least a soft reboot. The device is not rooted and is running stock 4.1.1. Has anyone else experienced anything like this?
As the title says, I'm having issues making calls when my phone is on LTE, when it's not it works just fine and I can make calls but as soon as it goes over to LTE again I loose the ability. My data works fine and so do txt messages just no voice calls. When I try to make a phone call the phone just sits there at Dialing.
I'm running Sphinx ROM atm however this wold happen when I was on CM11 also.
Any ideas guys?
With Miroslav's rom I perform calls without trouble. But there is one glitch...After finishing a phone call, I might lose signal completely and the phone will reconnect to the network. This usually takes about 20 seconds before the phone is connected to the network and ready.
After rooting my H815 (Vodafone UK) throughout most of the day I can't receive or make phone calls, the signal also at times during the day will completely go and I have to restart to get the signal back (which sometimes works) However I can text and use the Internet.
The main problem I've noticed is when I call someone it automatically goes to 3G and works but if it remains on 4G it will say dialing then completely loose signal then when I hang up the signal comes back.
Anyone know a solution to this?
I am having issues with the P8000 phones I have. The phone is taking too long to switch from 4G to 3G when receiving a call so it goes to voicemail everytime. If it is set to 3G only it rings perfectly.
Dialling out also takes an age as because of the long time it takes to switch, but due to there not being a time limit, it does finally dial after about 15-20 seconds.
Has anybody had this happen to theirs and was there a workaround at all? (They are using Telstra in Australia)
Also when you factory reset the phone it clears the IMEI info and you have to enter engineering mode to put them back, is this normal behaviour as I would expect a factory reset to leave the IMEI information untouched.
Hopefully someone can assist me with a workaround.
same thing here...

I'm having similar issue... the only difference is that I do not have 3g since I leave in canada and frequencies don't match.
Anyways, when I set my phone to 2g, I can call and receive calls no issues.
Once I select 4G, I'm able to make calls (after a while since the phones takes it's time to change from 4g to 2g) but I cannot receive... I'm assuming the phone does not know a call is coming since calls use 2d...
Hopefully this can be fixes soon.

update
after a conversation I had with my provider I may have identified the issue...
LTE does not carry over call service (only some provider through voLTE). So, when a receiving call is arriving, the provider sends a signal to the phone (called non assess stratum) that triggers it to change to 3g or 2g to receive the call.
when we want to make the call, the issue does not applies since the phone already knows we are making a call and automatically changes to 2g/3g.
so, will someone be able to help us on how to make sure the phone get the signal from the outside to change network type when an incoming call is arriving?
hope so.
thanks,
For the invalid imei after factory reset (or firmware upgrade), it doesn't happens everytime but it happens often. It's seems to be a problem with all mediatek based phones (it's the case on all my previous mediatek phones(5))
Cheers
I am experiencing the same issue re: no calls coming through when in 4G cause it doesn't switch to 3G in time and it goes to voice mail. (I'm with Telstra - Australia)
Has there been any update on this issue?
Currently I am in stock room.
My phone suddenly drops the network (Wi-Fi and cell network) but it is not in airplane mode.
I won't be able to receive any calls, but the caller will hear busy tone.
During the whole time my network shows few bars, but it is probably fake network.
I am just missing many calls due to this problem, and when some one notifies over other phone I will get to know and I will put into airplane more and back, the network resets and works fine.
Can anyone know what is the problem ??
I have reset my phone also, but of no use.
Thanks in advance.
