Hi everyone,
First post so be gentle
I got my dual sim honor 8 some months ago as I dont want to carry 2 phones around with me.
My personal sim and the phone are with Three UK and my work sim is with EE.
The three sim is in slot 1 and the EE simin slot 2 and I am finding the calls keep dropping for no reason on the EE sim. I can be in an area with full signal but when the call drops I cant dial out or receive calls. The phone goes to dial but just sits with the calling screen and then fails to connect.
After I have moved it works again, its generally happening in the same places too but places that shouldnt be an issue.
Whilst the sim 2 is in this condition I can still call out from sim 1 (Three) and this problem never occurs on sim 1 (Three).
I have tried swapping the sims over but the problem remains with the EE sim. I have tried to swap the 4g priority over but the Three sim is 3g only so wont work as the secondary sim.
I have spoken with my work IT and they have replaced the EE sim but this hasnt fixed it, I have called Three tech support who have reset this and reset that and run diagnostics and say nothing wrong with the handset.
Any ideas or any one else experienced this?
Many thanks
If it's from the EE sim card, then it's from them I believe

Could it be a temporary problem on their side?
Why don't you ask EE customer service?!

try only using EE sim in slot one and check whether issue persists?

Hi,
I have and they advise no fault, they have even replaced the sim card to rule this out.
Just try with a 3rd operator on both SIM slots: that will rule out hardware problems.
As for 3G/4G, operators use different bands, but you shouldn't have any problem.
If you have issues getting data or even a signal and you have MetroPcs (611) all you have to do is call metro and tell them to add your OnePlus 6 imei to your account and you'll be fine.

I'm assuming this applies for T-Mobile as well? My OnePlus 6 is coming within a day or two but i'm unsure if the data will automagically work when I put in the T-Mobile SIM for the first time

U don't have to do anything, just plug in Sim card and ready to go.
I use Ultra Mobile, a T-Mobile MVNO/reseller, and 5G is working for the most part, but I am experiencing the same dropped calls, missed calls and SMS/MMS messages sometimes don't come in or out.
There is this from T-Mobile regarding SA 5G:
https://www.t-mobile.com/support/devices/latest-sim-for-great-network-experience
My question is if they have provided MVNO resellers with these SIM cards as well... If anyone has any knowledge of this, an update would be appreciated.
(And I have received the August ROM update enabling SA 5G.)
Thanks in advance!

Even with the new r15 sim card you will still face the same issues. I'm on T-Mobile and have the r15 sim cards and when in SA mode, I can't receive calls and outing calls only last 21 seconds before hanging up. Also, you can get SA while you have an older sim card as well as I was getting SA even with the older TM sim cards. Personally I force my main device op8 pro to use NSA 5G only instead of SA and my test device tmo op8 to SA 5G for testing. I'm sure at some point the mvno's will get updated sim cards, just don't expect it to fix all the issues. I believe the issues will be another update from OnePlus, unless it's network side that's the issue.
According to tmobile it should be fixed by 9/26.
ImDonly1, What is your source for this being fixed by 9/26? I have a T-Mobile OnePlus 8 with the "new" R15 sim and I'm still getting dropped calls and no service errors

DNS may help but not always 5g won't really be out for another year
So the title says it.
I have the T-Mobile 8T and I bought a cheap little dual sim tray for the 8t and was wondering if the tmobile 8T will still do dual sim with that tray?
It's in the stock tmo settings app for dual sim so I'm hoping it works
Do you have 2 imei numbers?

I shoved my old 7T's dual sim holder in to my Tmo 8T with my two SIM cards (if you have Tmo, get your FREE LINE during the holiday promo...).
The sim holder didn't fit all the way in but the first sim card did register and it worked fine. The phone did not report seeing the second sim. I'm wondering if that's a function of the Tmo ROM. Looking in the sim card hole you can see there are top and bottom pins... I have to wonder if flashing to the global firmware would activate the second sim....

The weird thing in the stock tmo rom it has settings for sim2 and sim1 so I would assume it would work and yep that's why I'm asking this I got the free line lol
Having two Sims on the same network won't help you very much for performance, but it's great if you need two numbers!

Not only that, you could potentially use one SIM for data only ($20+/mo) and a second SIM for voice ($3/mo for Prepaid), instead of spending $60+ monthly. A different calculation on multi-line accounts though...
Unfortunately, I can confirm that, at least on the latest T-Mobile build (11.0.4.6.KB09CB), dual SIM does NOT seem to work.
I've tried it with the OEM dual SIM tray for the OnePlus 8T, which fits perfectly in the T-Mobile "OnePlus 8T+ 5G." The second SIM (SIM2 slot of the tray) is never detected and no options for it appear despite both SIMs working individually when placed in the SIM1 slot of the tray.

Fortunately, people have already confirmed that the Global ROM conversion does enable dual SIM. See the Global/EU conversion thread for more.

Damn oh well,I'll keep the tray and my free line sim stuck in the 8t and wait for twrp then I'll switch to global firmware and try dual sim. I really just want twrp for 8t on a11

Thanks for confirming what we suspected. I think anyone seriously interested in dual SIM should be on global anyways.
I bet that eventually a few smart devs will dig into the T-Mobile rom and find a way to patch dual sim support back in
The g100/edge s are listed as no Verizon support, but I was wondering if anyone has tried. They have most of the Verizon 4g bands and 2 of the 5g bands
If anyone is curious about this I have not confirmed but I did find a post where someone tried on reddit. Everything worked except receiving texts. Verizon was unable to troubleshoot because the IMEI was not white listed in their system. After doing some reading this leads me to believe cdmaless needs to be programmed on the SIM prior to putting it in the g100/edge s and it may work. This would require a cdmaless "mule" phone to preprogram the sim prior to installation. If I can find a phone to borrow I may purchase one and give it a shot.
Same problem here. I love the g100, amazing phone especially for the price, but cannot receive texts and Verizon refuses to help with an "unsupported" phone, even though it supports all the bands necessary for operation. 4G works, calls work, and sending SMS and MMS work. I'm willing to try whatever ideas to get this going. Been riding off my old phone as a hotspot for the g100 lately.
ah nice to see I'm not the only one in this situation. You already pulled the trigger though! If you can find a whitelisted gsm phone to swap your sim into and reprogram first you might be up and running. I've been trying to find the cheapest mule to try this with. Will update if a come up with one.
I'm not sure I follow. Why would another phone make this one work?
And I guess what are the requirements of the other phone? I could probably convince a friend to let me swap if it'll work
I'm not 100% sure but I think the issue you are having is the way the line is provisioned. It is most likely set to use the old CDMA radios (the g100 does not have them). Verizon has a cdmaless provisioning setting to get around this, but they can/will only do it for CDMAless phones they have added to their white list (while having compatible 4g and one 5g band the g100 is not on the list). If you put your sim in a white listed CDMAless phone you can get the proper provisioning put on by Verizon before putting it in the g100. This should fix in bound text
Ooh very interesting. I did find stuff for 'cdmaless' in my search to get it working, but asking Verizon to add it yielded terrible results.
So it seems like the cheapest options for this might be the Moto E (2020) or the Moto G Power (2021). I might try to pick one up next week to see if this theory works.
nice! My brother has a s21 which I think will work. Trying to find one that doesn't take 2 months to get
So I ordered a G Power, swapped sim cards and it couldn't receive texts. Activated on the Verizon website, which needed to text me a verification code, hilarious.
Anyway, it added the feature
Code:
CDMA-LESS DEVICE PROVISIONING
to the sim, popped it back into the G100 and... it works!
Great suggestion, drock3260
So when I originally tried to get this to work on Verizon and they insisted that CDMA-less doesn't exist, well, I guess they lied.
So uh, does anyone want to borrow a G Power for 5 mins?

Thanks for posting about this! I am on V and strongly considering importing an Edge 20 Fusion. This thread gives me hope that it will actually work.
yeah according to kimovil it has compatible bands. If you are still thinking of pulling the trigger good luck.
What about MVNOs using Verizon towers? I plan to use US Mobile SuperLTE. Will text messages work?
It only has the one main 5g band so no I don't believe Verizon mvnos are gonna work. I didn't really care about 5g as there are few towers around me, but I have had great 4g coverage with text messaging
I can give you the best and most accurate answer. I live in America I have a moto g100 there's only one way to get this phone and that is to purchase it through Motorola USA one model option only and that's a blue Moto g100 with 8 gigs of RAM 128 gigs of memory model number xt2125-4 the name of the firmware is North American retail absolutely no bloatware because it's straight from the manufacturer not a cell phone carrier and for absolutely everything to work on the phone 4G 5G the only cell phone carrier that works on is the T-Mobile network. You can use it on the AT&t network but you're not going to get Wi-Fi calling or the 5G Network. It is a GSM only. Absolutely no CDMA nothing will work on the Verizon network. It is the only phone on the American market that dual SIM. It does have NFC. A dedicated Google Assistant button with the fingerprint scanner on the side. One issue though the North American retail will probably be the last one to receive Android 12 but because this is the United States the Android 12 version we get will be very stable
I recently got a Chinese 8/128 Edge S (XT2125-4), and 4G calls/data/sms all just work for me on Verizon.
I had previously activated my SIM card in a OnePlus 8 Pro. So in my case it was already set up for CDMA-less / LTE-only service, and I just had to move the SIM card over to the Edge S and it started working right away.
I've never noticed the phone say it was connected to 5G, but I'm not sure if I need a new sim card, or if there aren't any 5G towers in my area (or both.)
