Mobile network not working properly while roaming - Sony Xperia XZ1 Compact Questions & Answers

I have an XZ1C with Havoc OS 3.11 (Android 10) GApps and rooted with Magisk. It works just fine as a daily driver in the UK. I'm with Tesco Mobile (which uses O2's network) and I get 4G signal (no VoLTE as it isn't supported on Tesco Mobile).
However, I'm currently on holiday in Crete. When I rebooted my phone I didn't have any signal whatsoever. It didn't work again until I set the preferred network type to 3G and then back to 4G again. Then it does work, but I only get 3G signal. My parents both have 4G signal though (my Dad has a Samsung J5 and my Mum has an iPhone 6S, none of which are rooted/jailbroken/modified in any way). They're on O2.
I remember LineageOS had an option to switch to 3G on boot and then back to 4G. That would have fixed my problem. But Havoc OS has no such option. Is there any other way to do this? Also, is there any way to get 4G working?
I don't want to switch to LineageOS or any other custom ROM as Havoc OS works almost perfectly while every other ROM I've tried has many annoying bugs (especially Android 11 ROMs).

Mi5 lte issue with all roms

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts
hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?
Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.
hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?
Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).
this is easy.
root then disable LTE band 41

How do you disable band 41?
Thank you in advance.
easy way > install network signal guru > 3 dots (menu) > lock bands > lte > uncheck b41 tdd 2500.

Mi5 under LineageOS no data mobile (4G, 3G...)

Hi, I flashed my Mi5 from miui 8 to LineageOS Nougat a week and half ago. I have the latest update which is dropped since April, 11th
Rom is very nice, but I have a huge problem. My operator is a French operator (I'm from France). Its name is "Free".
When I was under miui I had all the time either 4G or 3G when mobile datas were activated
Now since I am under LineageOS, I'm almost always in H and very rarely LTE. I never have "3G/4G". I don't really care about the name, but my mobile datas suck... I mean pages are very slow to load, like it should be in H.
I thought It was a problem from my operator but a friend of mine and I went together at the cinema yesterday and we have the same operator. He was in 4G and had a very nice network.
Mine wasn't able to load Google and I was H... (And he's got a UMI Touch running Marshallow Stock ROM)
What's the issue? Can you help me ? (We got the same Access point names defined)
Thanks, best regards.
Up... Haven't found a fix yet
Change your network settings under sim settings to "Global". Also if you are having network connection issues, try to change your APN.

4G doesn't stay, always return to H+

Hello everyone,
I just bought a Oneplus 3T and it's a really good phone, but i'm facing an issue : 4G only appears a few time (with almost full bars) but it's just coming back to H+ every time, i mean every time.
Usually i have 4G in that place, even with my old ****y Samsung Xcover 3 and its the same with another phone operator sim card.
What do you recommend for me ?
Thank you very much
Details :
French version
Up-to-date (Android 8.0.0)
Phone operator : Sosh (tried B&YOU)
Fix
*#*#4636#*#* use the diagnostic under phone information and move it to 4g/lte only
I've seen this solution but it's not a real one, no ?
If I put LTE Only, i will not have 3G/H/H+ and stuff if there is no 4G around me, right ?
Perhaps your ISP radio tower is far away, doesnt mean its phones fault
I had some issues with sim. I've to get new sim and 4g service reactivated
Well, as i said before, i was able to have 4G even with my old Xcover3 in that place, so it's not the network provider's fault.
4G is working on my Oneplus 3T, it's just that it's most of the time, like MOST, on H+ and not 4G even if I had 4G in thèses places before...
It looks like he phone auto balance between 4G & 3G as soon as 4G is a little bit weak (even weak, it's still beter than 3G anyway...) and I noticed that sometimes the data are just turned down (nothing DL, charge, but H+ still on status bar).
Im on Oreo stock OOS, do you know if there is any issues on this new version ?

No more 3G/HSDPA+ mobile network

For quite a while now, do I no longer get any 3G/HSDPA/HSDPA+ connection. I am unsure since when exactly it happened or what the cause of it is, but I am sure that I should be getting 3G, as I could verify 3G connectivity with other phones.
In the end, I only have slow 2G/Edge connectivity. LTE is not an option due to the lack of band 20 unfortunately.
I live in Germany and was able to try the networks of Vodafone and O2/E-Plus using different SIM cards, however neither of which got me a 3G connection, despite 3G being available in this area.
Also, for some reason using the hidden "Phone info" menu in android, you can select the radio band. There I only have the options "Automatic", "United States" and "Cellular 800". Setting it to anything beside "Automatic" results in no connectivity at all. I remember seeing more options here, like Europe and so on.
I am currently running a clean install of Omnirom (Android 8.1) and used Resurrection Remix (Android 7.1.2) before that. It stopped working when I still on RR. I have to assume something changed with more recent firmwares? I am currently running Developer Firmware 8.3.1.
same here on turkey, ankara, vodafone
I just reverted to stock official MIUI (tested both stable and dev) and neither had 3G connectivity. My old Galaxy Nexus had 4 out of 5 bars 3G/HSDPA+ connectivity at the very same location...
isnt the actual frame being used as an antenna? did I maybe dislodge (via dropped phone) the connectivity somehow with the "3G antenna"? Is there a sheet for this, what part does what in case I need to take it apart?

Verizon LTE with custom rom?

I recently signed up to Verizon prepaid with my Moto X4 Retail (XT1900-1) And I cannot get LTE on any custom rom that I have tried how do you get Verizon LTE?
I've tried LineageOS and Havoc OS, I seem to get 3G with Lineage and Nothing with Havoc OS.
Every time I pick the Verizon Internet APN and set it to LTE/CDMA it deselects the little dot by Verizon Internet on the APN screen and Nothing but 3G.

I'm on Tmobile and using LineageOS on my moto x4 xt1900-1. In settings under mobile neywork there is a toggle for advanced 4G LTE. Might want to see if thus is turned on. Wish I could help more. Good luck
That option is not there on Verizon with Lineage unfortunately, it is there with the stock Rom however.
The stock rom shows LTE. And i get about 9 mbps. I get 1.5 mbps and it says 3G on Lineage.
Im on Total Wireless, which is a Verizon MVNO, and can generally get LTE on nearly all custom ROMs. I have not tried LineageOS specifically, but have used ROMs based off of it.
If you are having issues you might want to try a full stock ROM with Magisk for Root, it's guaranteed to work better than Lineage and give much less issues. BTW, your LTE speeds seem rather low, unless Verizon Prepaid speeds are lower than a typical MVNO? I get 30-50Mbps Down and 10-20 Up.
I got LTE working on LineageOS but I had to install the stock rom first. Installing the stock rom and updating to the latest OTA and then installing Lineage seems to do something to allow LTE. However with Lineage there is an issue where the Carrier text is displayed as "Roaming Indicator Off" instead of "Verizon" if you switch preferred network type from Global to LTE / GSM / UMTS it says "Verizon" and LTE+ But doing this disables CDMA. Something to do with "ERI". I don't know much about it this is just what I found digging through some issues posted on the Lineage Gitlab. Someone posted a solution but I don't know if its going to get merged into the LOS main builds.
My speeds still suck. I get about 30mbps if i go outside but anywhere inside voice and text work fine but data is 1 mbps or less.
Edit: funny enough when my download speeds suck sometimes download is like 800 kbps but upload is 20 mbps+
I'm on Havoc 2.8 and my settings are as follows.
Mobile Date: ON
Roaming: ON
4G LTE MODE: ON
Preferred Network: LTE/GSM/UTMS
Wi-fi Calling/Video Calling: OFF (don't know why they are listed if it's not compatible w/ this phone)
Choose Network: Choose Auto is set to ON and there are no other values here
APN: Verizon - VZWinternet
CDMA Roaming mode: Audo
CDMA Sub: RUM/SIM
I'm not sure which are useful but with it I have both VVM and VOLTE working to my knowledge. I'm on Verizon post-paid.
