Thats incorrect, can be 2G/3G/4G, the other sim is 2G/3G.
To ther op's, for all I know, the P7 and 8 is full active, you can use sim one to call sim two and you phone will start to ring, thats the same for sim one on call, whiles data can be used to surf the internet on sim two. This feature has been removed for all released afterwards.

Thanks Bro, if the 2g/3g sim received a call .. the internet stopped working?
Example: Is the truecaller worked to identify a number call me on 2g/3g sim card?

Lets just say that when sim 1 is active (on a call), sim 2 is disabled.

Nothing can be done about it, of all the phone only Huawei P7 and 8, from what I know has this feature, all the newer Huawei has removed the feature, and other manufacture thinks it's not worth having it.

You got to give more details, majority of the phones posted here work with two sims at the same time.

is it possible / room enough to use a dual sim ?

i like to know if there is room enough above the sim to use a duosim from duosim.xcom ?
Anyone an idea?
come on , is there any room to place a dual sim ?
Oh, wow. That stuff looks cool. Now I'm curious too.
Yes, there should be room enough.
So, I've tried it and yes it fits but it doesn't work.
The TD has 8 connections to the SIM card and the Magic Sim (www.dual-sim.nl, 16th cut version) has 6 connections. It is 16th gen card which they propose to use for smartphones....
It works on my old Nokia 6021. This phone has 6 connections to the SIM Card.
The cutted SIM Card doesn't work anymore on the TD so I have to purchase a new one. I have sent a mail to dual-sim.nl. I will post the outcome.
number of contacts is irrelevant. Only 6 contacts are used for sim cards, the last 2 are RFU (reserved for future use).
If i read you right, after you cut up your sim card it doesnt work anymore? even directly in the phone without the dual sim? If thats the case your broke your sim while cutting it. The dual sim may or may not work still.
The cutted SIM doesn't work in the TD but does work in the Nokia 6021.
The Magic Sim doesn't work in the TD but does work in the Nokia 6021.
So, my assumption was that the cut is the reason that the SIM card doesn't work anymore on the TD. Strange that it still works in the 6021??
No, there is an incompatability between the magic sim and the touch diamond it sounds like. Only 6 contacts on the sim are used, the last two do nothing.
So if it works fine in your 6021 and not the TD, then its the magic sim that has the problem.
What error do you receive? no sim/insert sim?
SIM card is seen, Magic Sim program is available in teh TD but it doesn't register to the network.

Hmm thats really strange. What happens when you manually register?
It lists the available networks. KPN (my provider) in one of the them. If I try to connect to this netwerk the same thing occurs: can't register... I can try another network (roaming)?
Hmm that means the IMSI is not being passed corectly.
Sounds like a bug with the multisim itself. Another brand might work.
Not all new USIM cards works fine.
Put your phone on GSM mode instead of WCDMA or Auto.
Then the Dualsim works fine.

Due to your questions I tried it again and came to the conclusion that the cutted SIM card didn't work in the TD because it didn't contacted completely. I also saw a different kind of slide for the Magic Sim which leads to a better contact of the Magic Sim to the TD and now everythong works!!
Thanks someone1234 for taking the effort ask further

Thats great! no problem.
Does the Dual-sim 16th gen. non-cut version also fit into the TD?
I don't think my employer will appreciate it if I would cut my KPN sim-card of my company phone...
anyone tried the 20th gen dual sim adapters yet?

[Q] Dual sim issues

I have one sim that I wish to use for phones / text messages, and one that I wish to use for mobile data.
If I put either sim in on its own, it works fine.
If I put both in together, and set them so they are both on, the one that I wish to use for phone calls and texts does not register on its network (which is Three in the UK)
I am not sure what to do. Can the phone company have set it so it doesn't work in a dual sim setting?
Or have I just failed to understand what dual sim is?
Any help much appreciated!

Try interchanging the SIM, I mean just enter the right one on the left and the left one on the right. What you are saying shouldn't happen.
If possible try another 2 SIM to see if the problem is with the SIM or the phone.

OK thanks. I have tried it with another 2 sims and it works fine. So that means it's a faulty sim?
Is it possible the network won't allow dual sim, or should I just request a replacement?
Thanks

Before requesting a replacement just ask the network operator of that particular SIM that if they disallow Dual-SIM or not. If they don't allow using their SIM on a dula-sim mobile asking for a replacement would be pointless.
I am using 3 (UK) and Vodafone, no issues, so likely the sim

Mate 10 pro dual SIM

Hi there, i just got a BLA-L29 upgrade from a Mate 8. The main reason its that i need a dual SIM phone and the way it was implemented in Mate 8 was brilliant. Both Sims were active on the same time, if you're in a phone call on SIM 1 and you get a call on SIM 2 you get a notification and you can put the first call on hold and take the other one. Same the other way.
Can this simple set be achieved on Mate 10 pro?
The only setting i can find are just call forwardings between SIMs, that's more than lame as its costing money and not reachable some time (for one of my SIMS the provider only offers call forwarding to the voicemail, not a different number).
Thanks

Maybe something to reach out to Huawei about?
I would have thought this was possible since both Sims are supposed to be active, even on LTE, simultaneously. I just tried it however (receiving a call to Sim 2 while talking on Sim 1) and even tough I can manually put the Sim 1 call on hold, the call will disconnect as soon as I answer Sim 2.
Hi, I have the Dual Sim Mate 10 pro, but actually I only use it with 1 sim card.
However, I have a notification always present saying "SIM 1 call forwarding" - is there any way to disable this feature!
Thanks in advance

Mate 10 pro single sim
Hello guys. I have huawei mate 10 pro single sim, but it has 2 rows of Sim connectors.
My question is, is there any way to activate second sim slot? In settings "wireless and network" I do not have any dual sim option.
Do I have to upload software from mate 10 pro dual sim?
Regards for help.

Phone restarting...

I had this happen in 3 different instances:
1) Come back to the phone, which was lying on the table, to find that it was restarted. Happened 3 times in 5 minutes.
2) Another time, the phone restarted for no reason - I came back and it was asking for pattern instead of fingerprint because it restarted.
3) In a 20 minute drive, the phone restarted twice, which was announced by the Bluetooth car unit. I stopped each time and verified that the phone actually restarted.
At first, I thought it was me holding the power button wrong and it getting stuck.
But I have tried my best to not push the power button in any weird way, and then it still happened.
Moreover, here's an interesting exchange between, apparently, ZTE and users. Credit to oberio28:
5, sometimes the phone will automatically restart, how is this going?
A: We have located the reason and will resolve this issue in the next release, please update to the latest version to experience.

I am on NA rom v3.0 and I don't see a fix anywhere yet.
Anyone else?
It doesn't happen for me, Global EU 2.09
Just updated from 1.11 to 1.15 NA. Going to see if that fixes reboots.
Also, why the hell doesn't the phone remember the Bluetooth volume level? Is that a Pie thing?

Do you know anything about this problem?
"I use ATT as as carrier, and I tried several of their sim cards. As soon as I install the card, that Sim slot (1 or 2) truncates its IMEI from 15 to 14 digits, so it thinks that's it's a CDMA sim card. I think this is the reason why I cannot access GSM calling settings such as Call Forwarding. It says "Network or Sim card error."

I use ATT prepaid mine does the same but the last digit is a check, meaning once sim is activated it helps hide your full IMEI. I get 4g LTE and no Voice HD calling, hence it always reverts to 4g/3g in calls. Got to love US carriers.

Thanks. It was explained to me at an ATT store that Voice over LTE was not available for a prepaid plan.
However, can you change Call Forwarding settings (I cannot, and I am not sure what the problem is):
Phone app / ... / Settings / Calling accounts / AT&T / GSM call settings / Call forwarding / Voice
?
Mine gives me reply "Call settings error , Network or SIM card error."

Yeah I get the same error, I don't think it's phone though. My other phone is Poco F1 and its all custom ROM with no LTE bands and it does the same. But both can transmit/receive calls with same sim though...I think its more the network and not being AT&T branded phone.

Thanks. Here's more info that may be relevant.
1) Oneplus 6, global version, doesn't have this problem, that is not being able to set up call forwarding from the phone.
2) Whenever AT&T sim card is inserted into a slot (1 or 2), that slot truncates its IMEI from 15 to 14 digits by removing the last digit.
So, if without the sim card IMEI 1 is XXX...XXX5, it becomes XXX...XXX when the sim card is inserted into slot 1. Same happens to IMEI 2 if the card is inserted into slot 2.
