convert single SIM to dual SIM - Huawei Mate 20 Pro Questions & Answers

I've heard about this with the P20, can this be done for the Mate 20 pro?

Not currently.

Does anything changed?

From what I have hear it's possible for Mate 20 Pro, but I'm struggling to fined a source.
I Resiliently bought a secondhand Mate 20 Pro LYA-L09 that regrettably dose not come out with Duel sim and would really like to convert it to duel sim. Otherwise i might have to replace my phone again.
(First time poster was not sure if i should create new thread or bring this one back to life.)

Hi @Kalthrop did you find a solution?

Unfortunately not, one guy reached out but felt like a scam. Wanted me to send him the phone and was from another country.

[Q] Which HD2 to buy (UK)?

OK so I'm getting bored of my X10i as there is pretty much nothing you can do with it and I'm probaby going to go back to a winmo based phone.
I've had many x1s and loved that phone however I want something new, I've also have the Touch Pro2 and while it was brilliant I found the camera rubbish and it was just too 'thick'.
I've decided to go for the HD2 (I think after the x10 I wont notice a massive size increase, except screen obviously) however I'm stuck between getting a 2nd hand one which was on T-Mobile or Orange (UK for both).
The 'physical' branding on the T-mobile handsets seam less obtrusive so I think I'll go for that. My question is does anyone see a problem in getting an (UK) T-mobile branded HD2, debranding it and flashing costume ROMS & chaning the radio? I'll be using it on Vodafone (UK).
Thanks for the help, hope to be visiting this part of the forums more over the next few months.
you should have no problems at all with either, the phones are identical. might have to pay fifteen quid to get it unlockedbut that's it.
sam is the expert so no worries on that score. But i would advise caution on buying a second hand hd2. Just make sure the phone has no issues due to heat problems.
I know quite alot of hd2's switch off when they overheat and this results in normally needing a new motherboard etc. so make sure you test the phone before you buy it.
Good luck and i am sure you will luv your new phone.
Brilliant guys, thanks for the advise. Unfortunately I can't text the phone as I'm buying from CEX (I have vouchers to use plus I'm getting aboutn £200 in vouchers for my x10).
If the worst happens I have 12 months warranty or I'll just send it to HTC to get fixed... hopefully...

Ahhh i see. in that case mate i am sure it will be fine. It really is a great phone. Perhaps you should check out an energy rom?
Enjoy the phone!
I actually used the Engery ROMS on my X1 so I think it will be good to get back to it!
Thanks again guys!
I got mine from cex and it was on o2. Get a grade a stock as this is like new. Mine had the seal on everything even the phone hadn't been used on the network.then I went to the link on the o2 websiye and they give you the unlock code for free.

rebranded unlocked

Hi Team. Picked up unlocked m10 pro from UK store. Put my 3 sim network in there and it's totally rebranded as a 3 phone (boot animation etc.) And not a factory reset clears it down. Other sims work but I want rid of it really. Any ideas? Thanks
You can't now. Only way is to rebrand it European build C432
Boy I'm glad T-Mobile doesn't do that stuff here in the US!
It's because 3 mobile UK have an exclusive to sell it on contact I believe
Thanks for the input peeps. Rang Huawei and they said ring 3 shouldn't be happening and also swap device 'again' back at carphone whorehouse. I'm no stranger to flashing stuff but there isn't a great deal out there on rebranding to C432 as stated previous. Any decent guides? Cheers

This is the thread you need to rebrand, the other option would be to go back to wherever you bought tickets, swap it for a new handset, get Vodafone SIM, and make sure that's the first sim you install, it has no branding as such, just two apps which can be removed.

I bought one as well and it's also branded 3 but that's about it, apart from the Huawei apps it's fine
Are your wanting to rebrand because of the splash screen
Sent from my BLA-L09 using Tapatalk
the rebranding for 3 is for a reason i believe but not sure, i've still not received an update from huawei regarding the re-branding of the phones when you place a 3 sim in it.
i think the reason is to allow the phone to use the 3 wifi calling without the actual app, i pixel xl won't work on 3 unless i use the app, but the mate 10 pro works. I've also heard that the wifi calling features of the phone do not work on O2 without an app, so it could be for this reason the phone updates and installs their bootloader.

Experience with Funkyhuawei?

Hey guys and girls.
Does anyone have experience with Funkyhuawei with a phone that Huawei didn't give the bootloader unlock code to?
Preferably a Mate 20 Pro of course.
I'm thinking about giving it a try but I would obviously have no TWRP and no Magisk.

I got my phone from funkyhuawei, 8gb 256 gig model. They say they cant provide the boot loader unlock code as it is locked from Huawei. At this moment in time it is not possible to unlock it.
I used FunkyHuawei for updates for my P20 Pro with a locked bootloader since OTA updates never seemed to arrive and the service works well. Since they only have build 122 currently for the International Mate 20 Pro which I am already on I haven't tried it with the Mate 20 Pro yet.
Bootloader unlocking codes and rebranding aren't going to be offered for this phone and the rooted Mate 20 Pro phones they were selling apparently lose root the first time you update the OS so that was a complete waste of money.
I'm happy with the update part of their service but they don't respond to emails--ever. The best way to get FunkyHuawei updates is via Twitter.
I ordered an accessories bundle from them for the Mate 20 Pro but haven't received anything so far including anything to indicate that my order was ever received, processed or shipped (it's been a week) so the jury is still out on their store. The order was paid for with PayPal so I know they did get my money.
It seems like FunkyHuawei might be a one man operation.
I didn't know that they do sell physical products like a pre rooted device.
However, I did get a very minimalistic reply to my support request.
Since I don't know the service and the price of the root service for one phone is quite high, I don't want to risk spending money for nothing.

Replacement SIM tray?

Has anyone been able to find a replacement SIM tray for the 6T? I have the Tmo version and am looking to get the international tray so I don't have to hack mine up. Any leads would be appreciated!!
Much love , Haz3
Have you already tried asking Oneplus customer service? That's how I got mine. Some people have had luck with that and some have not so YMMV. Otherwise you can try cutting up the existing or use the closely fitting Oneplus 6 dual sim tray.
There are a couple of options on ebay, and I would say, they work as intended...

There's plenty for the OnePlus 6 on eBay US,but,I'm not seeing one listing for the OnePlus 6T,as of 12/8/18 (perhaps in some other markets around the globe?).
While the OP6 Dual-SIM Tray works on the OnePlus 6T,it's not a perfect fit.
If you have a link for the OnePlus 6T Dual-SIM Tray,there's a lot of us here who would be extremely grateful if you could post it.

No problem at all,was just hoping you'd found a source that was tucked away somewhere on eBay (or anywhere,for that matter). :good:
Just tried OnePlus customer support and they require an order number (which having the TMobile version I obviously don't have). Ridiculous.??

Yeah,that's where most of us end up.
I let it go after about 4-5 back & forths,but,their robo follow-up persisted,so,I started nagging them again,just for the hell of it.
I could tell they were growing tired of it & I brought up the robo follow-up as my reason for continuing the dialogue.
I haven't heard from a CSR in over a week now,whether it's a live/breathing script reader,or,the robo variety & nothing.
I have the OP6 tray,it's working fine,I'll patiently wait until the OP6T Dual trays hit the market.
Looks like the replacement OP6T Dual-SIM Replacement trays are now available on eBay:

You can order one from China cheaper... $10 for a piece of plastic LOL
OnePlus said they will send me a free one but it's been almost 2 weeks and still nothing

Yes but you will need to wait 2 to 4 week or pay 10 and it is in the US 2 to 4 days
Anyone who has actually received theirs point to a good source to buy the dual sim tray for the mirror black finish (glossy not matte)?

I didn't think to worry if it was glossy or matte. Just ordered from this seller. Thanks.
I had luck on ebay. I believe the one i received was for oneplus 6 instead of 6t and the edge where the sim button sits was just a bit longer than the slot on the device. I used a nail file to sand it down a little and it sits in my phone flawlessly now. Currently running dual sims, OOS Beta 14.

Noob Question: Dual SIM

I recently bought an unkocked Tmobile OnePlus 7T Pro and a replacement dual sim tray. I'm using Tmobile and SimpleMobile. I believe SM roams of the Tmo network.
The phone does not recognize the second SIM. I have read on the 7 Pro forum that the phone needs the "international rom."
I've tried searching here but haven't had any luck. I'm very new to this stuff, can someone point me to the thread/guide/download for flashing my OnePlus 7T Pro, so I can use my phone?
Just spent $500 on this phone and if I can't get it working, I will have to sell it and find another. Would really like to stay with OnePlus.
Really appreciate any help you have to offer, thanks!
If anyone knows that this is not possible, etc. feel free to let me know. I'm trying to find a different phone that supports dual sim, since my OnePlus seems incapable.

Hi I use my OP7t pro global HD1910 with dual.
He recognizes the 2 Sims and works very well.

Gonna be a little technical here. Going off the way my 6T works because it's somewhat the same. I have a TMobile branded 6T it doesn't support dual SIM out of the box while being on tmobiles version of OOS also it only comes with a single sim tray. I was able to convert it to the global firmware straight from OnePlus after unlocking the bootloader and installing TWRP and utilizing a tool called MSMtool which is basically the Holy Grail of restore tools. Anyway with being on global firmware I now have support for dual SIM all I would have to is buy a dual SIM tray. As for the 7T pro (I'm guessing McLaren edition with 5G as that's the only one TMobile sells) I'm guessing it works the same way TMobile locked out dual SIM on their version of OOS and shipped it with a single sim tray.
However we did just recently (as in the last couple of days) gotten a working MSMTool, nobody was really experimenting with the device because if you screwed up there wasn't much you could do, now that we have an MSMTool it should make it a lot less of a risk experimenting with the device and seeing what's possible. As for the global conversion for this phone I'm not sure how it would go due to the whole 5G stuff it's possible we get a global conversion akin to the 6T but there's a very strong possibility of losing 5G support (at least I would assume 5G bands in Europe are not the same as the US).
I'd say if you can wait to give it a couple of weeks to a month and see what develops I have a lot of faith in the devs that work on the OnePlus devices. There's also a dedicated forum for the McLaren edition now and I've been reading around about everything.
I apologise if I'm coming off like you don't know what any of these things are I'm just trying to explain it the best I can.
Hey, that was a great explanation. Thank you!

No problem homie anytime, I would highly suggest holding out and seeing how things play out, it's a fantastic phone (currently have my 6T but plan on upgrading very soon to the 7T McLaren) I have very high hopes things will turn around for the better very soon. If you have any other questions feel free to PM me I'll help out as much as I can.
Thanks! I love the phone but returned it today, as the dual sim is a crucial function for me. Once I get the $ back I might get the international one, or maybe a Samsung S10 or Huawei. Been using OnePlus for a long time but it may be time to move on haha
