Hi,
I'm new to the forums and this is my first post. I've been using RR Official on Radon for a few months now though, constantly updating along the way. I find my biggest concern right now to be having simultaneous 4G/3G on dual sim instead of 4G/2G as 2G is not an option in many countries.
I'm currently on RR 5.7.4 10192016, Radon Kernel 2.9.5, and CM 14 Firmware, which somehow allows me to have simultaneous 3G/3G, but for some reason both of the strength of their signals are always equal to one another despite being connected to different telcos, if one goes up the other goes up and if one goes down the other goes down (so I am doubting that it is true simultaneous dual sim 3G). For some reason neither of them can switch to 4G either, which I had access to before switching to CM14 firmware from CM13 firmware (which could only do 4G/2G).
I read in a whirlpool forum that MIUI added simultaneous 4G/3G for our device quietly and was wondering if any of the current custom ROMs/firmwares/Kernels allowed for this as I really need this feature and would prefer not to go back to MIUI.
I have the links to the forum, but unfortunately can't post it, being a new user.
Thanks.

Ok, first and foremost I'm not new to rooting for flashing, I did have a LGP350 that I rooted and flashed, it started malfunctioning (hardware issue) so I got a new low end Android phone from Walmart (Huawei U8652), I used SuperOneClick to Root it and installed CWM Recovery, now what I'm having problems with is that I wanted to use GSM networks since I have better GSM coverage in my area, since the phone has AT&T rom is doesn't allow me to select "only use 2g networks" (GSM), as a matter of fact I dont even see the option, so I was looking for a Gingerbread Rom for the U8652.
The forum doesn't seem to have a Huawei catagory, and its quite confusing trying to find anything.
Bump
Well I found 1 compatible rom (cyanogen_u8650-benru89v4), but Only use 2G networks and Network Preferences does not seem to be working properly, I tried to set network preferences to GSM Only but it wont stay on it. Is anyone else experiencing this with this rom?
Bump...??
Did I miss something in my research ?
Everything I read seemed to suggest that both SIMs in the Z7 Mini were 4G capable, in fact I am sure I saw some promotional material with screenshot of a UI display labelling both as 4G.....but is that only for TDD ?
I'm in the UK and independently my EE and Three SIMs can get a 4G signal on the phone in slot 1, but once I inserted both cards at the same time, activating the mSIM settings, the 2nd SIM is labelled as GSM only (1st SIM labelled 3G/4G).
Bought a pre-rooted model on ebay, not 100% what ROM version I have (phone advises there is a newer ROM available, but fails to install...possibly due to root status). Perhaps this works differently in a newer or custom (CM?) ROM. Anyone know ? When looking for cheap option for a dual SIM phone it was challenging to get clarity in the reviews and specs as to the parallel operation of 4G on such phones....thought I'd been through enough!
After a day of playing I can say it compares favourably (and gets a better AnTuTu score) with my Galaxy S5, fixing dual SIM would be great
Both SIM slots are 3G/4G capable but you can't use it on both at the same time, the other one will go on GSM.

thanks - searching again today I've found numerous sites which confirm the same... I clearly misinterpreted whatever I found first time round!! Assume no significant changes with Mokee or other ROMs
No, it's hardware limit.
About the ROM the stock one is only English/Chinese and there is no playstore, online store usually sell it with a custom ROM based on stock to add multi language and play store.
That's why the OTA update fails.
Last stock ROM is 1.76 but they are also developing a ROM based on lollipop.
I am using CM11 and I'm quite happy with it.

Recently ended up with this phone, wanted to use it on straight talk with a AT&T sim since it is unlocked.
It works, kind of.
I get one bar or no signal in places I have 2 or 3 bars on my old HTC one M8.
I thought about trying a different rom or a different radio if you can flash those on this phone. I am used to the unlocked bootloader on M8.
I even tried the aluminum foil mod around the battery I found on these fourms. Currently I am back on the HTC because this thing gets no service. Any advice would be appreciated.
Thanks,

Search the General and Q&A sections for unlocking radio bands, although I don't personally have experience with this - have just seen the multiple threads.
I finally managed to get into the Verizon hidden menu and enable all supported bands, 2 and 5 were unselectable but I think AT&T uses 4. Still getting spotty service, anyone know if any modems are better for gsm than whatever version is with the stock 6.0.1 rom? I've seen a few post mentioning 12b, is that the most stable or something?
How did you did that? Interested in getting 2600Mhz (if possible)
Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.

Jeff
I've got a XQ-CT54, I guess i was wondering whether if you put two sims in (lets say one esim and one physical), would the phone switch to the other sim if it lost singal on one?
This sony help guide page; https://helpguide.sony.net/mobile/xperia-1m4/v1/en/contents/TP1000669479.html
Suggests the phone can only have one 5G sim set for data traffic, but doesnt say what happens if theres only 4G available or no signal available for that carrier/network. Would it automatically switch to the other sim, or would you have to go in to the settings and switch it over each time?
Guess i was sort of hoping/thinking how good it would be to have a main sim on one network, and then another sim on another network and it would auto switch between the two if say 5G or signal was lost on one, but im guessing it wont work like that?
Thanks!
Awesome question!
PS: Would't even mind to switch manually but the stupid icons on the top screen don't really show useful information (just those crappy 4 bars loosely related to RSSI).
i guess it should work if you disable national roaming but I have never used 2 SIMs in one phone so.....
Where I live, if you have signal than it is usually present for all 3 carriers and during field work I needed multiple devices anyway so 2 SIMs would not help at all.
