Xiaomi MI PAD 4 LTE only connects 4G network when wifi is connected - Xiaomi Mi Pad 4 Questions & Answers
My MI PAD 4 LTE has this strange behavior:
- When WIFI is on and connected the tablet shows 4g connection indicators
- When WIFI is off I have "no signal" on the 4g connection
Some additional info:
1 - I'm on latest China Stable ROM (MIUI 9.9.26.0)
2 - I've tested the simcard in another android phone and 4g works flawlessly
3 - I've checked for IMEI blocking here in Brazil and my MI Pad 4's IMEI is or blocked
Any ideas or suggestions?
Hello fsworm,
I have a MI PAD 4 with LTE, too. There was a fake-Rom GLOBAL 9.6.7.0.0 installed (BANGOOD) to my PAD4.
Same effect as yours. SIM-Cards German O2 and German VODAFONE
Login to networks is not possible.
Same effect witch XIAOMI.EU - ROM 18.10.8 and MIUI stable China 9.6.27.0
Any Idea? Have you reached something?
Same problem, MIpad 4 LTE cannot access mobile network
I have the same problem. MI pad 4 LTE from China in use in the UK, it does not seem to register with the network provider, hence no access to mobile data.
The device comes from China and I have not unlocked it or changed the Rom.
Any idea?
Thanks!
Same here.
I AM in Portugal and i cant connect LTE without WiFi.
This is China ROM.
Stable version .
Any help?
mipad frequenties
I've the same problems. It seems that not all bands are covered like they should. When I go to another location I have connection, but it should also connect on my home adress.
The tablet came with the fake global rom and unlocked which I even didn't started. I've flashed first official chinese rom with fastboot - installed twrp - format data - installed eu rom MIUI 10.2 8.10.25. Everything works except the network. That's really the only thing I find really negativ on this tablet.
The used frequenties for mipad 4 plus should be :
4G LTE-64GB+128GB B1 (2100), B3 (1800), B5 (850), B7 (2600), B8 (900), B38 (TDD 2600), B39 (TDD 1900), B40 (TDD 2300), B41 (TDD 2500)
There is really something wrong with the software of this pad.
-deleted the other frequenties as they are wrong - information provided to me was wrong

So, with the EU ROM you also have problems with LTE network?
wtf, i think i will sell my Mi Pad
I am in Austria with China Stable Rom 9.6 and for me works Lte without enabled Wifi,no Problems with it
I have such a strange behavior last year with my Mi6 in Croatia.. As soon as I crossed the border to Croatia, I lost any signal.. Only with Wifi it showed connected.. But when we were at Zadar (~4hours) it suddenly had LTE connection.. I dont know why it didnt work before, but since that I have no problem

I thought the Mipad 4 has only Lte and no 2 and 3G?
Nobody shows 2 or 3G.

Related to mi pad 4 plus network not working
Its simple...since this mi pad 4 plus is LTE version... first u have to subscribe 4g in the sim card using ur phone (cellular device) . After that u can insert it in ur mi pad 4 plus...and it works.

So -just to be clear about what you say here- installing the Global Rom does not solve the issue of stability of mobile data? Have you also unlocked the device?
Because in that case I would spare myself the trouble of getting the Global Rom if it does not solve the issue...
Thanks

Correct - I was misinformed by a website that said that mipad 4 had these frequenties which was not correct. It is however really negative that there is no band 20.
Same problem, i have only signal with Wifi on (but can't use 4G), i use last xiaomi.eu rom
With wifi off, 4G is off
Someone can feedback xiaomi.eu team ?
Probably need upgrade for network driver
P.S : French network Bouygue Telecom, if i use huawei 4G router, the simcard work
@Asgardcfr 4g is off and you wonder why 4g is not working??? Really?
No you don't understand, when i switch off Wifi, i have no service in 4G but 4G is, of course, is ON.
It's probably a bug ...
After having plus model for almost two months and using it all over the country my conclusion is that LTE data does work when wifi is switched off. But.....
This tablet support only B3 band (1800MHz) and range and coverage of that band is usually worst than B20 band (800MHz). Everywhere. Add to that not exactly great reception of the tablet and the result is that with wifi on, tablet always shows network signal even if it actually isn't connected to a network. With wifi off, that is not happening and data does not work since it can't use B20 or 3G or anything else. But moving with it in area with 1800MHz coverage I do get signal and 4G label and data works again.
This was driving me crazy also, and I couldn't find an explanation why does it sometimes work and sometimes doesn't but after 1693758935 checks with Network Signal Info on different locations......
With wifi on but no B3 signal
a lot of bars but it's not even connected to the network
With wifi off but no B3 signal
zero bars, as it should be in the first case also. since it's not on the network
and outside of the house, wifi off but in range of B3 signal
......and connected to bonbon network

This is plausible, and makes sense, but the question is can it be fixed easily? Is it possible to modify the band?
Just to add: got my tab yesterday and put my Vodafone data sim in it - 4g/LTE worked perfectly well to download my apps etc, I got home and added Wi-Fi which was flawless.
Today I left my house with my tab in my bag and realised data is no longer working, after reading this thread it seems connecting to Wi-Fi has been a big factor.
Only adding this info as my data was working perfectly well before I'd connected to Wi-Fi initially.
I'd love a solution! Thanks
Ok as a pretty persistent person I may have found a solution - I am posting this response on LTE but this may be a premature shout!
I cleared all network settings using the usual menu, restarted the tab, connected to WiFi, turned wifi off then went to 'mobile networks', deselected the automatic network selection then manually scanned for and connected to Vodafone LTE. (Edit: wifi may have been on when scanning available mobile networks)
This seems to work. Since; I have reconnected/disconnected WiFi and restarted my Tab... LTE still working.
Hope this is a permanent solution for someone, so far so good here.
IMO, the only bug here is that with wifi on it shows network signal that it can't use while that does not happen with wifi off. But other than that, 1800 LTE works regardless of wifi status.

Does anyone own the Mediapad X1 4G? Would love some feedback on the device as well as
I've been going on YouTube to get some reviews but its mostly a quick hands on. Does anyone own the device and have any feedback on it? Any issues? I was thinking about getting the 4G version but I can't find anything on it! I've noticed the phone has been updated to a new version of android recently... Can you get root with the update? There's a 4G version of this as well, does that connect to the 4G bands of AT&T or does it just get HSPA+? I've been trying to look for the Chinese forums for this device to get reviews or user feedback in general but I can't find anything! Any help or opinions would be greatly appreciated!

I'm in the US and am on AT&T. The LTE bands don't work in the US so you would probably want to get the 3G version (Unless you travel overseas and might want 4G) If a huge screen and massive battery are your thing then get this phone. If not, your better served with the Sony Xperia Z Ultra. Other than Screen Size and Battery, the Mediapad X1 falls short in alot of areas. Pros Screen (Why else would you get this phone?) Battery (I get 3 days on a charge) Don't need a tablet Cons Poor performance (Compared to the current snapdragon equipped phones) Quirky Wifi Performance/Occasion dropouts (In the US) Old OS (KitKat is out, but fairly buggy right now) No custom recovery or roms (This would probably fix alot of the performance issues) High memory usage (Even after rooting and removing all the Huawei stuff) Just a little laggy in general (Annoying pause after unlocking the screen) Build quality is a little lacking (buttons feel cheap and are easy to accidentally press or hold)

Click to collapse I suppose "Poor performance" is relative based on the Antutu score, since I'm happy with the device overall. I did some exploring with ROM dumping tools, and I think I managed to successfully extract the /system partition. Still exploring though, hope to pick up some ROM modding skills.

I did upgrade to the leaked Kitkat build, it had some nice speed improvements however the DPI was set to 400 which was yuck, and the wifi performance was total crap. I had to go back to 4.2 unfortunately. It wasn't good enough for a daily driver, hopefully those issues get fixed for a proper update... The wifi issues on 4.2 are not that troublesome, with the leaked 4.4 rom they were very bad.

[Q] H+/LTE not working
Hi fellows, I have SM G-900T and I have an internet problem. I can`t use my internet(data mobile) at all. This version being from USA, I use it in Europe(Romania). Look at screenshot: http://sharemobile.ro/data/share/11008972_1620338411532587_716306529_n.jpg Is any method to use at least H+? Please help me. Thanks.
In Romania, only LTE Bands 3 (1800),7 (2600), and 20 (800) are supported. Orange (LTE Band 3 and Band 7), Vodafone (LTE Band 3 and Band 20), and Telekom (LTE Band 3) all support Band 3, but may not have it in use in your area. The 900T does support Band 3 and Band 7 in your region. So if your carrier is using 20, you are out of luck. As for H+, only UMTS (WCDMA) Band 1 (2100) is supported by the 900T. All the carries in Romania use UMTS (WCDMA) Band 1 (2100). All but one (Telekom), also use Band 8 (900) as well, which is not supported by the 900T.

It's possible you're in a region that is using one of the unsupported bands. Band 8 (900) is preferred as it has better building penetration then Band 1 (2100). Unfortunately if they are using Band 8, you will not be able to connect. Also, did you verify you're using a good APN? I don't speak the language, so I cannot find what APN Orange requires.
Thank you. Was from the apn. It works only 3G but is better.
3G is better than EDGE.
Nexus 9 LTE version - does LTE band 20 (or 8) actually work?
According to the HTC websites the supported LTE bands of Nexus 9 LTE version are: Bands 1,2,3,4,5,7,8,20 But when testing where only band 20 is available (using the Telia operator in Sweden) it only gets 3G. If I try the same SIM-card in my Galaxy S4 i9505 I get full signal strength of LTE/4G on band 20 (verified using the service menu). I also tried the Tele2 operator which actually showed LTE service, but from using it in my S4 again it seems that band 7 was the strongest band in that place. When I tried Tele2 in another place which should have LTE coverage on at least band 8 and possibly band 20 it again showed 3G... (I didn't try it in the S4 as I didn't bring all the tools and adapters to use the annoying NanoSIM standard). So does band 8 and band 20 actually work on Nexus 9? Otherwise it's going back to the shop because the lacking 4G support is not acceptable.
[HELP] 4G band rejection
Hello, I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India) It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier. Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM I unlocked Bootloader flashed old MIUI version and rooted my phone I installed Network Guru in that for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2 When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

Click to collapse My kenzo has the same issue with China Mobile(China). Failure at msg2 for band 38, band 40 and band 41. Currently, I lock it down to band 39 to get it work. I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine. Tried to flash the original ROM and modify the NV with QTSP but didn't work.

Is my H901 truly unlocked?
I got the H901 T-mobile locked off ebay about two years ago. I moved to India recently for work and will stay for a year. As a tmo customer i was able to permanently unlock it using the app it came with before i left the US. I bought a local sim card (Reliance Jio 4G) which uses 4G only (voLTE for calls and data). I checked the frequency bands before getting this sim and it supported 2 of the 3 bands. My problem is that it wont take to the network? (If there is a similar thread please link me to it). Jio LTE Bands - FD-LTE B3 (1800 +) (Supported by v10) FD-LTE B5 (850) (Supported by v10) TD-LTE B40 (TD 2300) (Unsupported) I think T-mobile mostly used the 2100 band for LTE in the US. Does this mean that my phone is not taking to the 1800/850 bands or is the cell phone provided not broadcasting over them and just using the 2300 band which is unsupported by my phone?
1) Found the service code *#546368#*901# played around with the bands. (Bands 2, 3, 5 and 20 were a success on this network even though only bands 5 & 3 are supported that was weird) - No luck getting 4G 2) Then forced Band 5 & 3 cause those are my only true options and did rat selection as LTE only. - No luck getting 4G 3) Kept above settings same and went to APN. Saw missing APN and googled the settings. - Success! 4G but no text/calls active. Trying to figure out how i can get voLTE on this now.
I found a work around with an apk from the service provider that handles calls and texts using LTE. But still cannot text or call using v10's voLTE feature. If anyone knows why i'd like to know. Otherwise, this thread can be closed.
