Inserting new carrier SIM -no data, no.update carrier config - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

S20+ unlocked from Samsung.
Switched back to Visible on the Visible+ plan, and getting no data icon at all. No data.
I had switched between Mint and Visible several times this year and it would always force a restart.to update carrier config after inserting SIM.
Not doing that now. Maybe the July updatr broke it?
Works great on my Moto G Stylus 5g.

Dual-Sim issue

I got this rather strange problem/issue with my G5. The 2nd SIM Slot it seems is not that consistent when it comes to network signal. I started noticing this when I put it my Roaming SIM on the 2nd slot, and there are times that it will randomly lose/gain signal strength and the network will totally disconnect. Then I have to again manually configure the network settings. That's when I decided to swap the sims I'm using. The Roaming sim works flawlessly on the 1st slot, while the local sim on the 2nd slot does the same, but so far haven't disconnected from the network, or at least once I noticed it totally lost signal for a second before going back to normal.
Is this normal for the Moto G5? This is something I can't argue with the store from where I got it from since the SIM is accepted and read by the 2nd SIM Tray.
The Moto G5 with Motorola firmware is currently being mis-sold, it is not really dual-SIM as you expect, the second SIM is more an internal storage location - you can switch to it but not use both properly at the same time. When connected with 4g to the first SIM the second is set to the obsolete and not available in many areas 2g. I have found that disabling the first sim is not good enough to allow the second to use 4g, you also have to set the second sim as the primary data SIM. The Moto app suggests you can choose which SIM for data or individual calls, guess it might work if your second SIM network is 2g only?According to report from Australia Motorola are aware of the issue and are looking into it - no 2g signal at all in areas over there. Elsewhere you may have patchy 2g signal and see the old data connections E or H popping up. Apparently older Moto G4 etc can use 3g at same time in second slot, not sure if the G5 issue is fixable by firmware or is some crazy hardware design fault. Don't hold your breath waiting for updates - Android 7.0 with January security update is latest here - while phone still under warranty!

Mi 6 problem - Emergency Calls Only (UK, Three network)

I'm in the UK on the Three network.
I recently purchased a Xiaomi Mi 6 (my current phone is an Mi 4) from Hong Kong Goldway. On booting it for the first time my sim does not seem to work with it. It shows 0 bars of signal, and says Emergency Calls Only.
I've not made any changes, and my sim works fine in other phones.
It's fresh out of the box, so no changes to MIUI, or to anything else. MIUI is at version 8.2 Stable, 8.2.2.0 (NCAMIEC). Android at 7.1.1 NMF26X.
I'd like it to work, but I also don't want to mess around with it too much if I need to return it!
Can anyone offer me help or advice?
How do I even return something to Hong Kong Goldway?!?
Have you tried it in the other sim slot?
Grab yourself a EE pay as you go for £1 and see if that picks up.
I have tried the other slot. Same problem.
Cheap sim is a great shout.
Updated to Global 8.5. Three sim still doesn't work.
Got a cheap EE sim, and it works in the phone. So I have a working Three sim (works in my Mi 4), a working phone (works with EE sim), but they will not work together. I've ordered a replacement Three sim just in case there's a strange issue.
Now the EE sim doesn't work anymore. It connected to EE, I received a welcome SMS and then it stopped working. I cannot make calls, or anything.
This is some odd behaviour I see:

Check out the top bar.
Between 1st and 2nd image I tuned on wifi/connected to my home wifi. It appears as if I am connected to a mobile network too. But I'm not. Still no calls/SMS/internet. Is this phone just broken?
Hiya, I'm using the Mi6 on ID mobile, they piggy back on Three, and I've not had any issues.
My phone came with the global ROM as well, and I've since gone onto the global beta. No probs.
I would say that the last few days there have been some network issues on Three around South West London, I'm having to turn mobile data off and on occasionally for it to actually connect. Though there's always been a 2G signal, so it doesn't sound related.
To be fair, once you've tried the replacement Three SIM, I can't see that it's anything other than the phone.
Fingers crossed!

Unlocked N9750 Dual Sim Mobile Network Connection issues with TMobile SIM installed

Hello,
I just purchased an unlocked Note10+ N9750 Dual Sim in Taiwan, and I am currently located in Taiwan. The phone is on the latest SOFTWARE update from September 1st. ...ASI3.
When I put 2 Taiwanese SIM cards in the phone, the mobile internet works flawlessly and is extremely fast (About 200/50 on each network) when selecting SIM1 or SIM2 for mobile internet, with WiFi disabled. I can switch the cards and it works as expected.
The icons usually show 4G+, although it can sometimes slip into 4G for 10-20 seconds or so.
However, when putting my Tmobile SIM card into SIM1 or SIM2 along with a Taiwanese SIM card, and selecting the Taiwanese SIM card for mobile DATA (The goal here is to use the Taiwanese SIM card for data when in Taiwan), the mobile data is extremely slow (Around 2/0.5).
Furthermore, most of the time, when trying to access the internet, it appears that the phone is trying to connect for the first 5-10 seconds before actually bringing back internet data.
This can be with an app, like Whatsapp, or a simple Google search, or a speed test.
The icons will show 4G+ or 4G, not sure there is a pattern here.
I have tried everything I could think of with roaming ON/OFF, moving the SIM cards around, etc.
APN for Tmobile is correct and setup for IPV4/6 for normal, and IPV4 for roaming.
Again, if I simply replace the Tmobile SIM card with another Taiwanese provider (2 Taiwanese SIM cards installed), the internet is super fast and instantaneous on either SIM card.
The Tmobile SIM is working as expected in a Note9 TMobile Single SIM.
Not sure if anybody has some insight on what may be going on here...
Coming from a Note9 and the Tmobile SIM is less than 1 year old if I recall.
Thank you.
I forgot to mention that if I go into the SIM DEVICE MANAGER with both a Taiwanese SIM card and the TMOBILE SIM card installed and disable the TMOBILE SIM, the internet works fast as expected on the Taiwanese SIM.
As soon as I re-enable the TMOBILE SIM card, the internet is slow again and takes 5-10 seconds before bringing data back from a Google search, etc...
That's because if you are overseas with T-Mobile it caps data speeds I believe at 256kpbs.
I'm guessing the order of the Sim somehow maybe coming into play . Also generally second sim position will give you Lower speeds
Hello Joogle,
I should have mentioned that I have the 15GB pass from Tmobile, so 4G speeds while roaming up to 15GB. The speed when on the Tmobile card is very fast, 50/10 or so.
This is not the issue I believe.
Does 2nd position really give slower speeds? I did not know that.
Interestingly, I am in China at the moment and put a Hong Kong SIM card in slot #2 with my TMOBILE SIM in slot#1. Selected sim#2 for data, and everything works great and is always fast.
Not sure what to make out of that.
Preferred Network is set to: LET/TD-SCDMA/UMTS.
A bit confused by all the options of 4G SWITCHER.
Well, I found out that if I put my TMOBILE SIM in 3G/2G mode only, and leave the Taiwan SIM card at 4G/3G/2G, everything works great and fast with no delay...
This is fine since 3G is good enough for phone calls and text messages.

Lineage phones that will work with AT&T 5G?

Dear Experts,
The cell phone I've been using
here in the USA is a Motorola G7 Plus,
with the Lineage 17.1 OS.
Yesterday, March 2, 2022, I couldn't
make a phone call. Immediately, the
call would end, and a message displayed:
"Call ended".
The folks at the ATT store in the mall
immediately suggested that I get a new phone.
My question was, why was I not warned about this?
It's been planned for a while now.
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
When are the carriers retiring their legacy 2G/3G/4G LTE networks? Here are the dates...
www.phonearena.com
However, ATT docs says that the G7 Plus will work.
Mysterious.

After swapping my SIM card with various
phones, turns out the issue is the Lineage OS.
Results:
...
Motorola G7 Plus, Lineage 17.1
- call ended
Motorola G7 Plus, Lineage 18.1
- call ended
Samsung Galaxy A32, out of the box Android
- calls work
Motorola G7, out of the box Android
- calls work
...
This is disappointing, as I like to use Lineage.
I've been looking at the Lineage compatible devices:
Devices | LineageOS Wiki
wiki.lineageos.org
Of the 165 phones there, many look to be a
number of years old, and would not be a
candidate to work with ATT 5G.
q1:
Is there a setting that I need to tweak to
make Lineage work with ATT 5G?
q2:
What current phones can be converted to Lineage, and
are now compatible with ATT 5G?
Is there a list/link?
Or does anyone speak from experience?
Thanks a lot
I found out that it wasn't necessarily my phone. Over the past 5 -7 days in my area and maybe everywhere, ATT was doing switching to eliminate all 3G. I had been warned last June that this was going to happen and even tho my phone was VoLTE and 4G, consumer cellular was adamant about making me get a new phone, so I bought their samsung A01for $100 just to shut them up. Consumer Cellular actually shut my service off, forcing my hand and that was when I was living down in Alto Texas. However, I didn't like their phone because it was all googled up and I went back to using my Moto G7 plus with LineageOS. It has been the phone I depend on and I like it best. When my phone stopped working a couple days ago, it was right after an update, so I assumed the update was the problem or my phone was haywire. Then, I found out thousands of people were having the same problem from https://downdetector.com/status/att/ and they do consumer cellular, too.
Now, the new minimum requirement is to be 4G LTE compliant.
After giving up on Moto G7 plus, I put my sim card into my old Galaxy S9+ and it worked. I made a phone call and talked for more than an hour. After I hung up, I tried to make another call and as soon as I dialed, I was returned the message, "call ended" and I couldn't get it working again. So I moved the sim card over to the phone that Consumer Cellular sold me last summer, the samsung A01 and no mojo. I messed around with it for an hour or so. Also, I forgot to mention that whenever I put the sim into a different phone, I would get a text message from Consumer Cellular letting me know that they have somehow configured my phone to work on their network and I have no idea how that works because when tried to show someone the messages they sent me, they were gone as if someone had deleted them and I had no idea that the sender of a text could delete the sent message on the recipient's phone, nor push a configuration. Long story short, nothing worked.
I stopped in at the local ATT store, today. The guy looked at my phone and changed 1 thing (my APN) and it started working. He changed it from Pure Talk USA (att.mvno) to ATT Nextgenphone (nxtgenphone). So now I can make phone calls and check my voice mail etc.... however, I am NOT able to use data from the tower. My wifi works, but I should be able to get data from the darn tower. no luck. I just wanted to let everyone know that I dont think it's my phone. I think it's consumer cellular and ATT or maybe just ATT because consumer cellular uses ATT towers.

Connectivity problem USA carriers

Hi everyone!
I've surfed all I've found here about Xiaomi Mi A2 Lite and the bands/carrier problems here in the USA, but I can't solve my problem. Here are the facts:
I have a Xiaomi Mi A2 Lite Global Version, Android 10 updated, not flashed, not root, works perfect and I love it.
I moved to USA from Spain 1 month ago, I got a new SIM from T-Mobile and the first two days worked, but suddenly lost the connection, not only data but calls and messages.
If I change that SIM with another one, (also T-Mobile, my boyfriend bought it the same day, same plan), then it works again but after some hours not signal again.
I've been doing this SIM change over the last 2 weeks, but it is really uncomfortable, I've tried to get a pattern but it doesn't depend on the time that the SIM is on the phone (it can be operative 2 hours or 2 days) nor in the data used or in the area.
When I lost the signal, the SIM is recognized but is like I was inside a deep cave with no coverage.
There is no way to recover the signal, I've tried airplane mode, rebooting several times, reinserting SIM, port change, even changing the SIM and changing it back, but nothing.
When I have signal I get T-Mobile 4G LTE and runs smoothly.
My SIM ports are fine because both read my Spanish SIM card, and the SIMs cards work perfectly because my bf can use both.
I don't know if is a network compatibility problem, he has a POCO X3 that supports the same bands and he gets signal all the time.
I bought a new SIM card from Mint just to check if it was about the carrier, and It does not work either, even when the phone compatibility says that should work.
I'm stuck now
Any advice? Should I buy a new phone to live in the states? (I'm going to be here for a year and I'm spending so much money on moving in that I would prefer not)
Thank you in advance!
