good morning ,
i bought htc touch pro unlocked and i inserted my AT&T but i cants see 3G in my phone and i just see E (EDGE)
i dont know why my phone support 3g bands
i have rom sense
pleeeeeeeeeeees help
and i tried my sim card into blackberry and its shows 3G
I HAVE unlimited data plane
3G doesnt work in my htc touch pro
Hi,
I had the same problem in the beginning. The simple solution: I still had an "old" SIM card, which was not capable of 3G. A simple request to my provider, and he sent me a new one (same tel number, no contract change / renewal) at no cost.

thank u but my sim card is 3g , i tried it into blackberry and it shows 3g
maybe this will help
go to start > settings > phone
then click on BAND tab and make sure the network type is set to WCDMA and the second drop down box has AUTO selected.
and press ok.
The phone should now look for the 3G network. Make sure you rem that if you are not in 3G network, your phone wont auto shift to Edge network, you would have to go back to the top steps and select GSM instead of WCDMA.
Hope this helps. If this doesn't work I bel there's some prob in the hardware or sim or the damn network itself !!!
I have the same issue
I have the same problem and i've tried radio 1.14.25.35 for at&t and with the same version for the rilphone.dll. i did find out that the version of the phone i have may be an issue. Raph100 (under the battery) EU 07/09/08 REV.EU01 (bottom left corner) under battery cover. I tried enabling hsdpa and hsupa. no help. i am using Energy.RAPHAEL.23563.Sense2.5.GTX.Themed.Apr.24 ROM. and i max at 50 kbps.
i did find some references with the phone:

Hello,
So i've got this nicely unlocked, shiny, G2x. (Running MIUI right now, please don't judge me) Anyways, I'm in Morocco, and am trying to use Maroc Telecom (IAM) which has 3g data (their site even claims HSPA+) and these are the frequencys they use:
GSM 900 / GSM 1800 / UMTS 2100
And copy pasted from the T-Mobile website, the G2x uses:
Quad band GSM (850/900/1800/1900 MHz), Dual band UMTS (1700/2100 MHZ Bands 1 & 4)
To me that looks compatible. Trouble is, i'm getting no data whatsoever, not even 2g, in an area that I know should have at least 3g. I've signed up for the plan correctly, I'm sure of that. And my G2x automatically picked up the APN settings when I first turned it on (and I verified that they are correct) but still not a hint of internet access. This is driving me crazy!! any hints would be greatly appreciated.
Just guessing, but does it think you're roaming. Maybe try enabling data roaming to see if it recognizes the data then.

It wouldn't be roaming if he bought a sim for that system as he says. Probably APN has a typo or not selected. Have to push radio button so it has a green dot to enable the APN. If that doesn't work then contact carrier to reset data on the account. I have had to do that in the past here in Thailand. Have you also tried turning the phone off and on, or doing airplane mode. Sometimes that is needed once.
Thanks for the responses!
Unfortunately, i've tried and double tried all those things, except getting the carrier to reset the data plan. I'll do that next. Now I just have to get through a bunch of menus in French & Arabic
Are you running Market Enabler. It can screw you up royally if you change sim and it was set to fake at boot. I had that on a Nexus One and had to factory reset the phone to get data working again when I changed sim.
Thanks for the advice. I don't think i'm faking my sim - unless that's something that comes with CM07 and I just don't know about it. Also I tried it on stock before flashing with no different result, so i'm pretty sure that's not it. Went to the office of Maroc Telecom, who replaced my sim (but still no luck) and an INWI sim which i'd previously been able to get 2g coverage on now gives me nothing. It is the weirdest thing and I feel stuck. Has anyone actually gotten a g2x to work on any other network?? is there some sort of Tmobile lock which is preventing me because i'm not using a tmobile sim? (And i'm not talking about the phone being 'locked', obviously i've gotten it unlocked, and can make calls just fine, and did have that short spell of 2g data on INWI) Anyways, i'm about ready to throw this very expensive phone out the window, because what is a smartphone without data?? Thanks anyways for your advice.
same, problem.
How can I solve it?
Maybe try to use other broadband?
I use my G2X in Thailand on TOT3G with no problems. They run 3G on Band 1 (2100/1900). Figure out what band it is. There about fifteen different 3G bands in use. Most people don't realize it but 3G radios use two frequency spectrums at the same time. There is an uplink and downlink. For example 2100 Band 1 uses 2100Mhz downlink and a 1900Mhz uplink. Band 4 is 1700Mhz uplink and 2100Mhz downlink. So the 3G radio in the G2X also transmits on 1900Mhz. But the 1900 Band 2 uses 1800Mhz as an uplink, which the 3G radio in the G2X doesn't support. Most companies that say they are on 2100Mhz are referring to Band 1. If they are running Band 1 the G2X definitely supports it. If you have sim unlocked the phone there is nothing preventing you from getting 3G reception on any carrier in the world.
Download "Network" (https://market.android.com/details?id=de.mangelow.network&feature=search_result) from the Android Market and run it. Scroll down to where it says what type of connection you want and make sure "WCDMA preferred" is selected. If the phone somehow got set to "2G only" you will never get 3G reception until you change it. That happened to me once on a Nexus One and took me a while to figure it out.
CM7 and some other custom roms are known to be having connectivity issues. I suggest you flash back to stock and make sure your apn is correct. If your apn is wrong in any way, the connection will be refused by the cell system.

Hey guys,
So I have the Z3 Dual, but where I live, we only get 3G network and no GSM, which brings me to my question:
Is anyone working towards a hack to allow my device to run BOTH my Telstra SIM cards in LTE mode without one reverting to GSM?
Thanks in advance,
Phil
Really? No gsm signal or 2g. I think 2g structures are the most basic one that every carrier Has. BecAuse if 3g becomes congested, the subscriber can fall back to 2g. Anyway i guess no hack is on going because of the rooting issues with this plus i think it's a hardware limitation. 2 simcards cannot use 1 modem (the 3g/4g) because that would tax a lot of battery power

There are 2 radios in the phone I'm suspecting, since both SIM's run different IMEI numbers (1 per radio) if you check in About Phone/Status and check the 2 SIMs.
So I can't see why this is a limitation.... renders the phone worthless for what I wanted it for (Work sim and Personal sim),
And yes, where I live, there has never been GSM, it was CDMA before the towers were upgraded to 3G (Central Wheatbelt is Western Australia).

When you use the first SIM with LTE the second has no signal?
I can't understand if the second sim limit is only for connection or also for 3G bands.
I mean: you can still use the second line on a 3G network only for calls and SMS without using data connection or not? The second line is limited on 2G bands?
thanks for answers I ordered a Z3 Dual 2 days ago

Correct, because the second sim drops down to GSM, which we don't have in rural Western Australia. And vice versa, set the second SIM to LTE/WCDMA and the first SIM drops down to GSM. Meaning, you cannot run 2 SIM's side-by-side unless you live in an area that has GSM/2G still.

So, you choose either SIM as your data sim. Whichever you choose, that sim runs in LTE mode and the other SIM is used for calls/sms only.
SMS and phone apps both have 2 send buttons labelled 1 and 2, so you can send messages or make calls from either SIM at the press of a button. But only 1 SIM has data active, that is the SIM running in LTE mode.
I have messaged Sony Mobile Developers regarding this, the reply was:

That's weird! If I live in a place with only 2G or only 3G network I cannot use 2 sim cards!
But I remember reading on online user manual that the 2 sims network settings are separated, right? If you force both on the right frequency?
In a few days I'll receive the phone and I'll help you with some tests

Correct, both sims wont run on 3G at the same time..
Both sims WILL run on 2G at the same time though (GSM).
i have problem with my data connection. when i set the preferred network to WCDMA only and LTE only. my phone has no signal at all. i have a strong 3G connection on my other phones.
is it a baseband problem?
if it is. how to flash the correct baseband for my F350L?
or this maybe a hardware problem?
thanks guys. appreciate who will help

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.

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..)
