Well, it not the fault of your phone. Tata Docomo has disabled 3g access effective 22nd January 2012 if you don't have a 3G pack activated. I had the same issue when using Tata Docomo 3G SIM in my data card. Have confirmed this from their Nodal Officer.
wat abt 2g connection?
ok...but y my internet works so slow in 2g network? when i had my previous mob nokia n73, in 2g alsi speed used to be around 10kbps but in this phone tata docomo speed wont be that much. due to slow internet none of my application works properly. opera keeps saying that unable to load page check network settings......even in stock rom i had this problem....
is there any way to fix this problem? plz help me. without internet i feel very boring....
I've been having this same issue with docomo. I recently bought the galaxy s2 and my 2g speeds are very bad.. Is there any fix for this?
I am using htc one m8. it supports 3g and 4g. but whenever i turn on 3g the network signals got disconnected. what is the reason and what is the solution. i have to restart my phone and after some time it becomes perfect. plz help me fix this problem. it is currently working on android 4,0 kitkat version.
Well that might have something to do with your carrier or it could be hardware. You can register if you like and ask your question here
Good luck
I'm from india.
Im using BSNL carrier on nexus 5. I have kinda strange problem on my phone. When i select only 2G mode i am not getting any signal.but if i change it to 3G or LTE im getting 3g signal. But in some areas in city 3G not available only 2G is available but im not getting 2G signal. I changed carrier to IDEA and VODAFONE still facing same problem.2G not working only 3g.
But in airtel and reliance 2G working ok.
For solution i have flashed new rom but not working also flashed RADIO files provided in xda forum but still same problem.
If u have any idea what to do please tell me.im about to swith my carrier due to this..
Thank you.
I would love someone to help with this strange problem, before I throw this phone in the bin!
First the specs.
Doogee x5Pro, Android 5.1,
Baseband DOOGEE-X5pro.2015/10/08
Kernel version [email protected].2015.10.08
Build number DOOGEE X5pro-Android5.1-R08-2015.10.26
The phone works fine when I set Cellular Settings / Preferred network type to 2G. Of course it only works as a 2G phone in this mode.
However, if I set the Preferred network type to either 3G or 4G (recommended) then as soon as I try to make a call or send an SMS, the modem radio turns off and the call is immediately dropped or Messaging says the SMS service is unavailable. Occasionally the called phone will ring, but the call drops immediately. Sometimes the SMS does get through, but at my end it appears that the modem radio turns off and on again as soon as the Dialler or Messaging tries to use it. If someone tries to call me, the phone rings and caller-ID is displayed, but as soon as I answer, the modem radio cycles off and on again, and the call gets dropped.
If I am in an 4G LTE coverage area, then 4G data works fine (browsing was fast, Speedtest was showing 85+Mbps) but I still cannot make or receive calls, or send SMS's - as soon as I try, the modem radio cycles off and then on. If I am not in an LTE coverage area (but am in a 3G WCDMA coverage area), then the phone just constantly cycles showing 4G for an instant then 3G, then radio off, then radio on but no service, then 4G etc... - this cycle is very regular and takes about 53 seconds end-to-end. If wi-fi is on, this cycle only starts if the modem is accessed (e.g. by trying to make a call), or by turning wifi off and cellular data on. And of course I can't make or receive calls or send SMS's during this cycle, and even when the signal shows 3G I can't get any data connectivity. While it's doing this, if I go to Settings / SIM cards, the 'On/Off' slider moves to 'Off' when the radio cycles off, and then moves back to 'On' again.
In summary; in 3G or 4G preferred network mode and not in LTE coverage, whenever anything (calls, SMS or data) tries to use the modem it cycles off and on again. When in LTE coverage, data works but calls and SMS cause the modem to cycle. As I mentioned, 2G is fine.
I think I've tried most of the obvious things, and some not-so-obvious ones. These are the things I've tried so far.
Obvious things like reboot, battery out, reset to factory settings, wipe cache, clear application data. No change.
I swapped the SIM from Slot 1 (LTE/WCDMA) to Slot 2 (GSM) - the behaviour was exactly the same (this surprised me as it seemed to be LTE-related).
I put my SIM in a carrier's (Vodafone NZ) Samsung 4G phone and it worked fine, also it was fine in a Chinese-brand 3G phone. Then I put another Vodafone NZ 4G SIM in my phone and it had exactly the same problems, so I think it's the phone rather than the SIM or the carrier.
Because data works fine when in LTE coverage, and the phone does ring if called (but cycles the modem immediately when I answer the call), it seems the hardware is possibly working OK. So I assumed software or settings might be the cause.
I created new APN's using carrier-supplied settings. No change. I flashed various Doogee stock ROM versions (don't think there are any custom ones for this phone) and they all display the same problem, rooted or otherwise. I've used the engineering menus (*#*#3646633#*#* and *#*#4636#*#*) to change bands, network preferences and various other settings with no effect. 2G (GSM only) is the only one that works. I installed the Xposed Framework and Gravitybox module and had a play with some of the settings in there but again, no effect.
I don't know what else to try and I can't return the phone as it costs too much to send it back to China from New Zealand.
So any help anyone can give me would be greatly appreciated, otherwise I'm stuck with a not particularly useful 2G wi-fi phone.
Thanks in advance.
Just a bit of an update. I've discovered that 4G LTE works fine when in range and 2G works fine all of the time; but 3G just doesn't work at all and I have no idea why - I've searched the threads and tried all of the suggestions I could find that can be applied to this phone. As soon as anything tries to access the 3G radio (calls, SMS or data), the modem just 'reboots' (powers off and on again).
All of the other symptoms I've described are related to this. When out of (or in marginal) 4G coverage, it starts in 4G, falls back to 3G and that's when the modem 'reboots'. When in 4G range, data works fine but as soon as I make or recieve a call it needs to drop from 4G to 3G (I don't think we have VoLTE here) and that's when the modem 'reboots'.
So any ideas anyone? Is this likely to be a hardware problem with the phone?
Thanks.

Good to see another Kiwi with a Doogee X5 PRO. I have not seen these issues in Auckland but a few weeks ago I upgraded to R17 using this ROM :
www.needrom.com/download/doogee-x5-pro/
I noticed 3G and 4G are much improved and I could get both in either slot 1 or 2 (I use dual Voda SIMS).
Last week I went Android6 (32-bit) using this ROM:
www.needrom.com/download/android-6-0/
Using this ROM I can only get 3G and 4G in slot 1 and 2 is "locked" to 2G .. so I guess its software based. If your comfortable with flashing your device then do the R17 upgrade or see if its available OTA

Hi, thanks for the tip - I've already tried the various ROMs on NEEDROM and currently have Android 6 installed, unfortunately the modem still exhibits exactly the same behaviour. But good to hear that yours works OK in NZ because that reinforces by belief that it must be a hardware issue (rather than a network one). Unfortunately this means the phone's only really any use as a WiFi 'phablet' or a 2G phone. So I've given up on it and bought a cheapo Voda Smart Prime instead, which does the basics OK - shame really as I've had Doogee's before and they've been really good. Oh well
I have just gotten an X5 Max Pro. I've noticed that I only have 3G service from my carrier in my area and for that reason I cannot receive calls if I set the favourite network type to 4G(recommended). I have to set the preferred network type to 3G in order to be able to receive calls, otherwise you will receive the "the phone you are calling is off or out of signal" notification, at the same time that I receive a text message from my carrier notifying the lost call.
To me it seems that the phone is not capable of downgrading the signal automatically to 3G when there is no 4G signal. However, I can make calls and receive text messages with no problems at all.
When I have 4G coverage, everything works just fine with the preferred network type set to 4G(recommended).
Is this a software or a hardware problem? I really don't know if it is related to the problems already described here with the x5 pro, but I have decided to post my experience. Maybe it will give some more hints about what is wrong with many Doogee x5 devices.
Thanks
Possible explanation & solution
Hi,
I may have an explanation and solution.
I have Doogee X5 Max Pro and I ran into similar problems. Doogee international did not respond to me, but their agent in Israel did.
Apparently in each cellular provider uses two frequencies: 2000 for outdoors, and 850 *or* 900 for indoors. High end phones support both 850 and 900 (along with the 2000). This model only supports 900 (and 2000), which means that you'd if your provider uses 850, you'd have a good reception outdoors, but a lousy one / none indoors (along with a higher battery consumption etc.).
The solution was to switch to a different provider that uses 900 frequency, and that indeed solved the problem (in Israel I switched to Partner - used to be a part of the Orange network) .
I hope that helps.

I think Yossi hit the nail on the head there! Ouch!
In Oz we have Telstra on the 850MHz band and Optus etc on the 900MHz 3G band..
So Optus is OK but Telstra nay.
The trap is they may show heaps of signal strength but it is probably from the wrong band!
You can do everything except make or take a phone call!
A lot of problems with phones has reared it's ugly head since the 2G network shut down.
Unless you have plenty of 4G signal (which the various providers share the same bands), you would be pretty stuffed..
I wonder if firmware(Rom) changes could solve the problem ?
(I also have the Doogee x5 max pro..)
Hello,
i often have the problem, that 4G (LTE) is propably aviable but the signal is weak and the Mate 8 switches to EDGE but the 4G Signal is sufficient for fast speed internet and so on.
Now the stock ROM has only options to force 2G and 3G in the net settings but not to force 4G.
Is it possible per app or mod to get these option? Or better: is there a custom baseband version or modification for optimized 4G reception and/or that the Mate 8 accepts weaker 4G signals and doesn't switch back to 2G/EDGE?
Thank you.
