Help, i think that there's something wrong with my phone. The signal coverage of my phone is sometimes missing without any reason, and will appear a minutes later or will appear if i set my phone airplane mode to on and off again.
I tried to use move my simcard to my other phone and there's no problem with the signal.
The problem is 'cause you have a not 4G SIM CARD, and the phone is trying to get 4G signal. To fix this:
1. Get a 4G SIM CARD
or
2. Go to Network Menu and select 3G prefered.
I got the same problem and i have 4g sim. I don't no what is the problem. In my case may be the methal bumper but after change it with one from silicon i still got the problem. May be the thempered glass from back of the phone?
I got the same problem and i have 4g sim. I don't no what is the problem.In my case if i select GSM in mobile network its working fined but if i changed to WCDMA i have signal problem /

Isn't there one of the option where it chooses either WCDMA or GSM?
LTE (preferred)/WCDMA/GSM
Tap >> settings >> ...more >> mobile network >> preferred network type
Check the setting is 'LTE (preferred)/WCDMA/GSM'
And not 'WCDMA only'
And not 'GSM only'
Also if you are using a dual SIM phone like I do then do this:
SIM1 = 'GSM only' where the network is a GSM one.
SIM2 - 'LTE (preferred)/WCDMA/GSM' where the network is a WCDMA one.

Having a problem here. i don't know if its the phone or the network. Im using C6833. I just changed my sim card for a GLOBE LTE sim (Philippine) ., but upon switching on LTE/WCDMA/GSM it will scan network but after 5 mins it will lost its connection and will not scan any network again.. but in a settings of WCDMA/GSM my network run smoothly., can you figure out what is the problem? thanks for your help.,
Sorry for reviving ths post, but I have a problem close to what OP has...
When I click LTE/WCDMA/GSM. It cannot detect any 4G signal, goes to 3G. Then, the option reverts back to WCDMA/GSM.
I tried the SIM card on another phone, and it can detect 4G signal.
Would appreciate any help.
i have a problem about my 2nd sim. i have two sim card and both are belong to the same network carrier. 4g indication is only shown on 1st sim card. when i turn the prefered data sim card to 2nd sim, 2nd sim always on 2g connection even lte is prefered. i swaped the sim cards and 2nd sim still shows 2g conncetion, so the problem is not about sim cards or carrier.i checked that when i put the cellular network to manual mode instead of automatic and data is selected sim 1, 4g networks appear in the search list. when the sim card 2 is selected as data and search for network, only 2g networks appear in the list.
sim 1 4G sim 2 2G OK
sim 1 2G sim 2 4G Not OK. both sims work on 2G (or sim 1 is 3G, i can not see any indication on top )
i checked the *#*#4636#*#* testing mode and both prefered network types are selected the same "td-scdma, gsm/wcdma and LTE"
when i bought the mobile phone, i had not got such a problem like this. i made imei repair operation and my phone works like this after imei repairing. i also test my imei numbers on both sims and still the same.

I have exactly the same problem! I had bought the phone from a chinese vendor and I hade 3G only in SIM1 and 4G in SIM2 . I used a guide and flashed a global qcn and restored the IMEI cause it was lost and after that I face the exact same problems as Salagil
Hi am Haruna from Ghana.
I bought Alcatel Ideal 4060a (AT&T) model a couple of months ago, but problem is that the network doesn't change at all its always at 2g/EDGE no matter what i do or which network i put inside the phone.
Am currently using MTN (Scancom) which is a 4g Sim card and the phone is unlocked to any network.
And there is no option in the settings that you normally choose from your preferred network mode.
So i stated googling for the solution when i came across this code (*#*#4636#*#*) which i can use to change my preferred network, but whenever i change it, nothing happen, i mean nothing at all, all it does is that, when i select "only WCDMA" i will not get service/network, when i select "LTE only" no network, the only thing that work is GSM or WCDMA preferred.
So guys i urgently need your help as am getting frustrating by this phone.
E/GPRS is slow max u can get is 28KiBps, switch to 3g or 4g, it also depended on your att network coverage, Are you living inside bunker?
Hello everyone, I think I made a mess...
I have a Le Max 2 X820, I went to the secret menu (*#*#4636#*#*) > phone info > 3 dots menu > select radio band > and i selected "band mode 6". All of this because I had 4G signal issues.
I thought I had solved because the 4G worked perfectly but I just found out that I can not make calls! While I try to call someone it loses the signal and displays a network error.
I tried to reflash the ROM, to flash another ROM with all the wipes, tried to reflash stock modem.zip but nothing! I am desperate! Please help me
EDIT: On the second SIM slot it works, I can make calls
EDIT 2: if I do a manual network search in slot 1 only appears 4G but if I do a network scan on slot 2 appear 4G, 3G and 2G so I can make calls
I did what you did 2 weeks ago on my x829,i think both options band 6 and usa bands just disabled 2g and 3g bands and i can get it to work with qpst or qxdm easily.

My phone's mobile network is keep switching from 4G to 3G and 2G, I turned off choose automatically and register on sorted 4G but no correction to the problem, I even dialed *#*#4636*#*#* and choose LTE under preferred network in phone information but network is still switching to 3G and 2G. Any other solution?
