I just bought HTC T328W from eto talk. It has dual SIM and I am under impression that GSM SIM works in both slots for audio/calls. Its just data connectivity which is 3G/WCDMA which is slot 1 only. In my case, when I put the GSM SIM in slot 1, it does not recognize it, however, same SIM works in slot 2. Wondering if I am missing something as to why SIM slot 1 is not working? Anyone would like to share thoughts or their experience, would be appreciated.
Is it an older Card dor Slot1!? Or 72k, on mine buying from eto too, both working!
Hi,
Same here... I just received my T328W... I am/was very happy with it, except for the 3G issue:
First time I put in a 3G card in SIM1 it worked for a few seconds (showed the arrows next to 3G). After that I was unable to get 3G working. Since yesterday SIM1 doesn't work any more. I tried several sim-cards (which do work in other phones)...
Hmmm... Just as I'm typing this reply, I removed the battery and waited for e few minutes: THIS DID THE TRICK! SIM1 detects the SIM again!
Good luck!
Its working now
Guys, thanks for the feedback. Actually its same what I discovered. SIM-2 works OK if you change replace SIM card by simply shutting down mobile phone. But SIM-1 doesn't work unless you remove the battery before installation.

Hi all,
Just got my Zenfone 2 yesterday and was super stoked, however the SIM2 component is not working. I have two SIM cards, one with Telus and one with Virgin Mobile. (Canadian carriers). No matter which order I put them in, the SIM2 card never works. The Zenfone 2 is able to identify the phone number associated with the SIM card in the SIM2 slot, but it is unable to actually make a network connection.
Anyone know how to get SIM2 working?
just update to the latest rom... I did and got my Sim1 working again!!

SIM2 is 2g only. So it needs to be Rogers (or network that uses Rogers) to work

Only SIM card slot 1 can access 3G/4G/LTE data. SIM card slot 2 can only be used for 2G service which include voice and basic text messaging (Not multimedia messaging services MMS or internet browsing). http://www.asus.com/us/Phones/ZenFone_2_ZE551ML/HelpDesk_knowledge/

I know this is an old thread but i was wondering if anyone has found a solution to this issue? I am having the same issue trying to get Sim2 to recognize a network. The number on the Sim card is recognized. I have tried switching the cards around and the result is always the same. Both providers that I am with are in Canada. One sim is with Bell and the second is with Virgin Mobile.
Are you saying you can't even make calls on sim2?

Hello
I hope this is the right place to ask and I feel at this point I have been searching Google dry over the past week.
I have a HTC one m8 with dual SIM, as I live in Sweden and work in Denmark, I have a Swedish tre.se in SIM1 and then a Danish 3.dk in SIM2
While I'm in Denmark, both SIM card works and connects to their network, but the second I enter Sweden, SIM2 won't find a connection.
I tried to switch the two cards, but then it's just the Swedish card in SIM2 that won't connect.
From what I have been able to Google , SIM2 should only be using 2g network, but this should be a problem for either of the subscriptions as far as I know.
Is there some special trick, setting or some I need to do to make it connect to 2g
It is original OS on it. I unfortunately can't root it, as my company mail will detect it and block my access. (Worx home by Citrix + touchdown)
What I have tested so far:
Factory reset of the phone.
New SIM card for both cards.
Activate and deactivate flight mode.
Deactivate and activate each SIM from the dual SIM manager.
Switch cards in slots (1->2 and 2->1).
Disable SIM1 ( SIM 2 still didn't connect)
I have also contacted each phone company, but they were to no use and just said it should work hehe
Any suggestions or ideas ? I'm open to all suggestions that doesn't involve getting another phone
Also this is not one of the cheap Chinese dual SIM versions.
Thanks
I may have managed to get a little closer to the cause.
It seems that SIM2 is actually only running over GSM / 2G for god knows what reason, and that is not supported by my phone company i Sweden, which is why it only works in Denmark.
I will try with another phone company called TDC and see if they have the same issues over there or else its bye bye useless dual sim
Hello there,
Im getting trouble to get the dual sim working properly.
First of all my setup : OOS 3.2.7, rooted, some xposed modules, nothing fancy. Stock kernel
SIM1: Data SIM, o2 germany
SIM2: Just used to receive some texts, all APNs deleted, Carrier : Orange/Sosh France
In normal usage SIM1 is deactivated. In this case everything works flawlessly.
As soon as I activate SIM2 i run into trouble. I loose data on SIM1 almost instantly and the only way to recover it is usually a reboot.
When i loose data the "LTE"/"H"/"3g"/whatever icon disappears, data is still on in the settings.
I noticed that at least once both sims were connected on UMTS when it occured.
Any clue to keep my data connection working when both sim cards are active?
Thank you in advance
Hello
I tried flashing my p8000 but i was not careful and did not flash correctly. I had problems with TWRP and ROMs.
I spent a lot of hours making things work and i finally i got a stable TWRP with a stock ROM working. Problem was that i lost both IMEIs and could not use the SIMs.
I started searching for solutions (chamelephon, MTK Droid Tools) but nothing seemed to work. I came across a post stating to sent specific commands from android terminal and i finally managed to make the phone showing the 2 IMEIs.
So far so good but again i cannot make both SIMs to work. Only the SIM that has cellular data connection is working. If I switch data to other sim card, the previous sim stops seeing network and second sim is working.
Anyone has any idea?
Cheers
ps. Also, not sure if I am correct or this has to do anything at all, the MP0B_001 file is stored in the path /NVDATA/NVRAM/MD/NVRAM/NVD_IMEI/MP0B_001 from the root directory (NOT root folder) and not in the path ROOT//NVDATA/NVRAM/MD/NVRAM/NVD_IMEI/MP0B_001 as stated in a guideline.
Hi, you can only use one sim on 3g/4g and the second on 2g. I had the same issue in the UK. For example the Three network sim only works with 3g/4g connection as this is the requirement of the network operator. I have 2 of their sims and only one can be connected to a 3g/4g network and the other does not support 2g therefore gets no signal. For your case if one of the sims can operate in a 2g network then assign the 3g to the other and the 2g on this one.
Hi, I have a A4 lite with latest patches febraury) installed.
since 2 weeks I have a second sim card and it worked fine until a few weeks ago.
my setup is
voice and text message sim1
Data Sim 2
since a few days I'm not reachable on sim1 but on sim 2, only if I switch data to sim1 too, I'm reachable again on my mobilenumber.
I changed the simcard already and got a new one from provider but this did not help.
However I recognized when I switch sim1 to only 3g not 4g it works.
so what could be the issue, and do you think it is a provider ot HW issue?
thanks in advance
