Hello everyone, is there a custom ROM that has 4G LTE support? I rooted my Samsung M30-M305F and switched from One UI 2.0 Android 10 to Lineage OS 18 Android 11. Now my 4G SIM calls end immediately upon dialing while data works perfectly fine. Also, my 3G SIM works perfectly fine for both calling and data. I have tried all SIM swapping combinations but still the 4G SIM doesn't place calls. Thank you.

Ting on Atrix 4G
Hello everybody,
I've signed up for Ting, a better alternative to StraightTalk I believed. I tried everything I could think of to make Ting's SIM card work with CyanogenMod 11 on my Atrix, no such luck. I then flashed back to the stock rom, reluctantly, thinking I would be able to make the SIM work before flashing back to Cyanogen. This is also a failure, so it seems like to me that Ting will never work on my Atrix.
I cannot make calls, there is no Mobile Network it states. I don't care about data or messaging, all I need is for the voice to work. I've tried numerous APNs and nothing is working.
Anyone else out there running Ting on their Atrix? I'm not one to quit so after 2 days straight of this I'm ready to throw the phone against a brick wall to force myself to stop working on this lost cause.
Appreciate anyone with any insight to offer. Thanks
TracFone's SIMs also don't work on the Atrix. They are deliberately locked down to work in their own devices ONLY.
OK, from the day I bought the phone, I was not able to connect to any 4G LTE network.
I tried MIUI (obviously), CM13, Slim, AOSP, etc and was not able to connect to 4G network.
I even used this method to fix LTE issues: Link.
I am currently testing all the ROMs available. Flashed about 8 different ROMs today itself.
Any fixes/workarounds?
Thank you!:highfive:
Dear Community , I’ve just bought a P9000 smartphone and I’d like to ask a question: as far as I know this dual SIM phone can not support 4G (or even 3G) when both SIM cards are inserted but to me the only way to have 3G or 4G capabilities is to insert the SIM card in slot 1 (the outer one, the same slot of t-flash memory expansion)… Is this behaviour normal? I thought that , with a single SIM card inserted, didn’t matter which slot was used to get 3G or 4G working on phone, and this is a severe issue because if you want 3G/4G capabilities you have to use slot 1 and therefore no more t-flash into the phone… Please, could you help me? I tried with engineering mode (BSPTelephonyDevTool) but no joy at all... Thanks in advance, best regards.
I have always had my sim (Three UK) in slot 2 as I use a 60GB SD card and I have had no problem getting 4G tbh. Altho the 4G connection was never really as fast as I expected & very ocassionally it wouldnt attched to a 4G connection in an area with 4G (but this was kinda very very rare)
Sorry I dont have a solution to your issue, but on a side note I have just installed the Andriod 7 Beta to test it out and I can confirm that the 4G is outstanding on that, even the 3G is way faster with a much much better signal - better than I have ever experienced on any other ROM to date. (same with the GPS, its spot on)
What network are you on & what Stock ROM (I'm assuming your using stock with you just buying it) are you using? the latest Stock?
Thanks for prompt reply, to be honest the phone belongs to my sister... Anyway, the P9000 is on TIM (Telecom Italia Mobile) network operator and android version is Marshmallow 6.0. At the moment the issue still remains, I think that she'll be waiting for Nougat 7.0 to come on OTA...
few days before i rooted my redmi note 4 , when i reboot the phone i found that jio 4g sim is showing NO SERVICE. i replaced with new jio sim but same problem, even i did all the settings correctly. then i tried airtel 2g/3g it worked fine. i flashed my phone many times with all global roms of different versions, also i flash modem but still nothing happened. so i need some help, please tell me what should i do now?????
Well if you have tried a different SIM from Jio itself and different roms, it should mean that there's probably no 4G connection available where you are.
I have a RN4 (Germany) and I have zero issues with connecting to 4G networks here, even from the prepaid SIMs.

Problem: Sim card stops working after making a call. Can't receive calls either.
I just bought the Mix 4 around two weeks ago and just put in a new SIM card that I just got today. The SIM card was already tested to be working fine on my Vivo NEX S. Calls, text and data all work fine with the Vivo NEX S. When in my Mix 4, it works fine when it comes to data and texting. But when I try to call, the SIM card just stops working. The Mix 4 is able to detect it, but it's unusable until I put that SIM card inside my Vivo NEX S and then putting it back in the Mix 4. When attempting to call with the Mix 4, when the call goes through, the SIM just turns off or is disabled. But the call will go through and I will be able to talk to the recipient for a couple seconds before it stops due to lack of data/loss connection. I also can't seem to receive calls.
I also have a working Verizon sim card and the exact same thing happens. I've also taken a look at the APN and everything looks fine.
Is there anything I can do?
Sounds like a phone issue.
Same here, just got my T-Mobile sim card today and mix4 shows no signal.

Based on feedbacks from Reddit and xiaomi forum, I notice it only occurred for US carriers.
I tried verison, at&t, and t-mobile, but none of it worked.
MIX 4 seems to have issue for network registering, which renders it unusable in US.
