Mate 10 Pro GSM / 2g network connectivity issues - Huawei Mate 10 Guides, News, & Discussion

my mate 10 Pro (C185 UAE REGION) has suddenly lost GSM or 2g connectivity on both sims simultaneously. I connects fine on WCDMA & LTE (3g/4g), however when GSM (2g) is selected signals disappear with a cross (X) sign on both sim slots.
Software was updated last month in November - 20 to 10.0.0.180 with July-20security patch. I have hard rest the phone to factory settings, rest all network settings, taken the device to service center but nothing has helped so far.
Have also engaged with network providers and replaced old sim with new sim but issue still persists.
I used to keep phone on 2g or GSM to conserve battery & for coverage in remote areas where 3g/4g services are not available as I have to travel a lot because of the nature of my Job, but now I have to keep both sims on 4g at all times which affects battery adversely....
Could anyone out here please provide some solution.

Also facing same problem here.. Any help from any one? Thanks

[Q] HTC S710E 3G Network problem

Hi,
I never test with 3G SM before with my phone.
I have changed my Vodafone plan to 3G and started using it.The SIM is working fine with 3G in my old mobile (Sony Ercsson).
When I put the SIM i my HTC it is not detecting 3G Network.If I choose GSM/WCDMA it is selecting the 2G Network and for WCDMA Only option
it is not showing any network.
Please note I am having the HTC mobile fro HTC Hongkong and now using the same in India.
Operator: Vodafone
Activity Performed:
Restart the phone and put off the battery multiple time
Factory Reset
Use another 3G SIM which is also workng in my old phone
Toggling between flight mode and WCDMA.
Results:
Just received the 3G network twice and it was sustained for 20 minutes and so.
Please note I am having good 3G Coverage in my locality and with my old phoe it always come full signal.
It happens some time
I have to disable / enable 3G to make it works.

Is Moto G 2nd Gen 2014 incompatible with Three

When I put my Three SIM in my Moto G 2nd Gen 2014, I can't get a signal at all and it doesn't list Three under Networks. Is this phone incompatible with Three? If so, that's a major downside as Three is the most competitively priced (3p/min, 2p/text, 1p/MB) in the UK and I would have probably bought a different phone if I'd known this.

The only Motorola phone listed on their site is the Moto G 4G. They go on to state "If you're using a phone that we don't have in our device support, we may still be able to help you set it up. Your phone will need to be unlocked so you can use it with a Three SIM. If you bought your phone or Mobile Broadband device from another network, you may need to get it unlocked before you can use it with a Three SIM.
To do this, you'll need to contact your old network and get an unlocking code. They might call it a DCK or Depersonalisation Control Key."
Here's the page I referenced.
http://support.three.co.uk/SRVS/CGI...cat=billing,varset_subcat=3772,Case=obj(3714)
Thanks but it's already unlocked. It seems Three use 2100Mhz and as far as I can tell, this phone doesn't support that frequency, although it's hard to find definitive information.
This US site refers to the Global GSM Model supporting 2100Mhz for UMTS/HSPA+ but not for GSM/GPRS/EDGE but I'm not entirely sure what that means in terms of using it for phone calls, not data (which I'm using an EE SIM in SIM2 for, although that only has 100MB/month free, so I was intending to use the Three SIM if I needed to exceed that) http://www.motorola.com/us/smartphones/moto-g-2nd-gen/moto-g-2nd-gen.html
I can tell you it definitely does work on Three Mobile as I use Three in mine, Three Mobile is a 3G (and 4G) only network if you are using two SIMs in your phone it can only connect one of them to 3G at a time which if you are using the EE SIM on 3G the Three SIM will only show emergency calls only.
Turn off the phone and power it back up with only the 3 SIM in SIM1 that way it should definitely get a connection, if it doesn't the SIM card may be deactivated or you don't have a 3 signal where you are
(you could also try with both SIMs in the phone go to Settings>SIM cards> then under Data Behaviour set Mobile Data to whichever the 3 SIM is in)
If you want to use the EE SIM for data and the 3 SIM for calls essentially you can't Three is a 3G only network so won't work in this phone unless you have the 3 SIM connected via 3G then the EE SIM connected to 2G which has a 2G network.
This is the UK page for the Moto G 2nd gen http://www.motorola.co.uk/consumers/mobile-phones/Moto-G/motorola-g-gb.html it supports GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz) and UMTS/HSPA+ (850, 900, 1900, 2100 MHz) it supports all the bands all the networks use for 2G and 3G
It can be a tad confusing with bands and such it doesn't matter about the GSM for Three only the UMTS/HSPA+ matters.

Ah thanks, that clears that up. Shame I won't be able to use it with the EE SIM in SIM2 for data though. I'll have to choose between the free 100MB/month with EE or using the Three SIM for cheap calls and texts (and data if I need to exceed 100MB/month). Problem is, if I just use the Three SIM it was pretty pointless me getting a Dual SIM phone!
I'm at home most of the time, so I only leave the EE SIM on 2G (to save battery) to maintain connectivity to things like Telegram and IM apps in case someone wants to contact me and then I turn the WiFi on if I'm going to be doing anything substantial. It's useful occasionally when I'm out to be able to check e-mail, use Maps, etc but it'd be rare for me to exceed 100MB/month so it was ideal really. With Three, that 100MB/month would only cost me £1 but every little counts.
If I set Mobile Data to SIM1 (Three) and enable both SIMs, it alternates between the 3G symbol and H next to SIM1 with three bars, whilst SIM2 (EE) has full bars. If I deactivate SIM2, it also greys out the Mobile Data button, although it stays in the On position, so I'm not sure if it's deactivated or not. I still see the H symbol, occasionally changing to 3G and three bars for SIM1.
After doing this, if I switch Mobile data back to SIM2 (EE) (which again disables the Three SIM) and then go into Mobile network settings for SIM2, I can no longer switch the network type to 2G, as it only shows 3G.
If I switch the SIMs over, so SIM1 is EE and SIM2 is Three, with Mobile Data set to SIM1, then both are active with SIM1 on full bars with no symbol, not even H and SIM2 on 2-3 bars with the 3G symbol. SIM1 is set to 3G and still the 2G option is missing, even though it must clearly be on 2G as SIM2 is using 3G and SIM2 has Data disabled, so I don't really understand why it shows the 3G symbol.
Looking more closely at the Mobile network settings shows that SIM2 is actually still the EE SIM and SIM1 the Three SIM, which is weird as they're definitely the other way round. If I enable Data on SIM2 (EE) that cuts off SIM1 (Three) again, so there's no advantage in swapping the SIMs over in this way. In theory I should be able to put the EE SIM on 2G, which would at least keep my IM, etc apps connected at home and then be able to use the 3G for the Three SIM for voice calls and switch the Data to 3G on the Three SIM if I need more speed when out but it doesn't seem to be possible, as the 2G option disappears for EE with both SIMs in but is there when using the Sainsbury's SIM in place of the Three one. So it seems that if SIM1 only works on 3G, as Three does, it forces SIM2 to use 3G as well and as the phone can't provide 3G for both SIMS, it prioritises the data SIM2 and disables SIM1
I can't say I've done as much testing as you but mine shows the same as yours if I set the EE sim to data I cannot force it down to 2G only any more where I could if it is the only SIM in SIM1.
But I know how you feel, over Christmas I was temporarily on EE because of a free data offer and it was very annoying having to have my 3 SIM turned off so I could use the free data and then every so often having to turn the 3 SIM on to check for missed texts, luckily most people use WhatsApp which wasn't affected because that's data based, but still it was inconvenient.
Yeah, I had that EE Christmas offer, something crazy like 200GB/2 months. I barely made a dent in that
Even with my Sainsbury's SIM in SIM1, if I disable that then the EE one in SIM2 (with Data enabled) gets fixed on 3G, with no option to change it but as soon as I enable SIM1, the option comes back.
I guess what I could do is give everyone my EE number to call/text me on, then only disable that and enable the Three SIM when I need to make an outgoing call or text, instead of paying EE's crazy 30p/min, 12p/text. The disadvantage is that if anyone tries to call me whilst the EE sim is disabled then it will go to voicemail and I'll have to pay 30p to listen to it! Not to mention being fiddly and a pain.
So I might see if I can use the EE SIM for data alongside an Asda Mobile one at 8p/min, 4p/text, 5p/MB as I don't make that many calls or texts (I tend to use Chatsecure instead) and I don't anticipate using much data over 100MB/month anyway.
EDIT: Seems that Asda actually uses the EE network, lol. So I guess that should work fine in SIM1 as a 2G call/text SIM, whilst the EE one works in SIM2 as the 2G/3G data SIM.
Sounds like a plan, I personally would steer clear of giving people two numbers cause that would probably end up being a pain for you and them, I agree ASDA mobile is probably your best bet for a call/SMS SIM that uses 2G.
PS the Dan and Phil SIM it was haha I cannot remember a single bad joke or random fact they sent whilst on that :laugh:

I joined Three as a network yesterday and have had nothing but trouble getting any sort of signal inside my house. I occasionally get some, and if I want to receive data I have to go outside. I have never had an issue when I was on O2 as a network. The crux of the matter is that I cannot receive data of any sorts inside any building. Is this the same problem you faced? If so, was there a solution?

No it's not the same problem, your problem is just a matter of signal, where the masts are, I'm on Three and get a signal in my house aOK but Three does have more of a problem with indoor signal because they only have a 3G network and only on 2100MHz meaning it doesn't go through walls very well, other networks have old 2G networks on 850MHz that travel through walls great and some have 3G on 900MHz. There is no solution really I'm afraid, you can use Threes WiFi app so you can make calls and texts via WiFi and you may be able to get a femtocell but that still uses your internet.
Coincidently Threes LTE network uses 800MHZ and 1800MHz so travels through walls far better than their 3G network does.

Apparent Data interference using 2 LTE sim cards

I have a dual sim Note5 locked with smart (but suprisingly, it is not really factory locked. I was told that I should place smart on sim1, but i tried just placing globe on sim2 and it still works even without a smart sim). I know that you can only use one (1) LTE sim, so globe is set to automatic, meaning it will be in GSM mode, since Smart is in LTE. Anyway, both sims are set to AUTO (LTE/WCDMA/GSM) mode.
Note that Smart sim1 is in LTE Band 1 2100 and globe sim2 is in LTE Band 3 1800. Both sims are LTE capable, and with existing LTE data plans.
Any way, here is the issue:
I noticed that i could not get a data connection using my smart sim everytime my globe sim is present.
Thus, if I have two sims inserted (smart LTE sim in sim1 and globe LTE sim in sim2, both set to AUTO LTE/WCDMA/GSM), LTE data access on smart (sim1) would work for maybe a minute or two, and afterwards, it would no longer connect to LTE. Even if the phone displays a 4G connection, it does not really connect (after a minute, no LTE connection). Because of no data connection, I would try using my Globe LTE sim (smart on sim1 becomes GSM), and surfing in LTE appears to be continuous, unlike with smart (using LTE in sim1).
When i switch back to surfing using smart LTE (Globe becomes GSM), i can again surf using smart LTE for a minute or less than 2, but eventually it will disconnect. Even if the phone says 4G, i cant connect to the internet.
Today, i removed the globe sim, and it seems that i can already surf with smart LTE, without disconnection of LTE data. I noticed that i can now use LTE continuously (using sim1) after physically removing the Globe LTE sim card.
My question is, is there some form of signal interference between two (2) sim cards, that prevents me from using two (2) LTE sims (both are set to AUTO LTE/WCDMA/GSM, and LTE is in sim1, GSM in sim2) at the same time?
Does the presence of two (2) LTE sims (although one is in GSM mode) affect the LTE data connection?
This is really a strange issue and hope anyone has already encountered this.

network problems

Hi,
i rebrand my P9 eva-l19C900 to c432 with success and i upgraded my android's version .. but i still have a problem with my network when i activate the 4g on one sim after twice minutes the second lose the signal and become deactived.

In Settings / Wireless & Networks / Dual SIM, see that only one SIM (you can choose which) can be 3G/4G
Hence one SIM will be on 3G or 4G, second SIM must be on 2G - but if your operator for that second SIM does not provide 2G you will not be able to use that SIM
In Settings / Wireless & Networks you can disable 4G and in Preferred Network type you can force GSM (2G) only - that way you can test which of the two SIM cards / operators provide/have 2G signal

In Dual SIM Settings you choose one which is 4G, the other will be 2G/3G
Cannot help you more, I have both SIMs 2G/3G/4G, hence no matter how I set, both work
Try playing yourself, test both SIMs one by one only, in one and the other slot, with various settings (4G enabled/disabled, Pref net 4G, 3G, 2G only)
Maybe you have problem with one of the SIM cards or one slot

Network data on Samsung S20 FE 5G after Android 11 update

I updated my Samsung S20 FE 5G to latest firmware Android 11 via OTA. After update, the network data stopped working on sim1 tray. I can receive calls, send/receive text messages, but no network data. I reset network settings, made factory reset, it did not help. Strangely, when I insert same simcard into sim2 tray, the network data works fine. I did not have this issue before update.
Is anyone experiencing same issue and how to fix it?
This happened to mine but not always. Traced the problem today : LTE band 3 and 1 work fine, LTE band 20 no data (on Three UK). Pushing my phone to 3G/2G (network mode) and then switching it back to the original setting, in my case LTE/3G/2G fixed it (at least in the last hour or so anyway).

I am with Three UK too. After switching networks from 2G to 3G, then to LTE etc fixed my mobile data issue. However as soon as I travel to area where 5G works, the network data stops. It seems this update affects 5G modem and generally mobile data
It's since reoccurred on mine after restarting phone. Not a good sign for this update/S20 FE
Yep same issue also three UK hopefully there's a fix soon this update also broke my duelshock 4 contoller ability to work with phone,rubbish update
only issue ive had since the update was the one day of ridiculous battery drain, other than that, smooth sailing
