I recently switched from my GS2 (AT&T) to an unlocked GS3 (Verizon), but I couldn't find an APN listing to match my service so I used HiAPN to backup the settings from the old phone and used the same app to apply them to the GS3. It is now not allowing me to make or recieve phone calls, or even access the 4G network on AT&T. It says I'm trying to make international phone calls when I dial out, when I answer calls no one can hear me, but I can still text. I have the phone set to GLOBAL, should I set it to GSM?
1st thing to do is set it to Global mode! 2nd if you google AT&T apn you will find one around that you can add and 3rd you should not save a received call(Edit it to put the 1 after the plus sign) or call back after receiving a call as it doesnt input the number 1 after + so it makes it +(zip code)
And this phone only gets EDGE on AT&T
Hello all,
I flashed my girlfriend's Sprint S5 with Lineage OS recently without a hitch, all services working perfectly. We ended up traveling, so she went to Sprint to set up a temporary international roaming plan. Everything was completely as expected abroad. When we got back, her phone would not send SMS messages.
We tried the usual airplane mode and such, and to no avail. Assuming something was wrong with the network configuration from travelling, we reset network settings. Didn't work. I then decided to just do a full wipe and re-flash of Lineage OS. Still doesn't work. I then resorted to going back to the stock TouchWiz ROM from Sprint. At that point, under the stock ROM, SMS were sending. Out of curiosity, we flashed back Lineage OS, and SMS will again not send. We noticed that if the SIM card is removed, SMS will send, but the phone would not be able to access 4G LTE. We also confirmed with Sprint that there are no restrictions on the account.
What could be causing this to occur only on custom Roms? Do we need to do a PRL update? If so, how does that work on stock Android?
Thanks in advance!
S5 sprint No outbound sms
I've had this problem for weeks....So far the only solution is using Google voice app....
I'm using LOS 7.1.1 20170207 kltespr nightly, LTE SMS can only receive, sending doesn't work. Only 3G SMS works.
Things I noticed:
Settings -> About Phone -> Status -> IMEI Information. When on 3G, all information is displayed here, when on LTE, only IMEI and IMEI SV is displayed, there's no PRL/MIN/MEID/ICCID anywhere, not even disabled or greyed out, just hidden completely.
ICCID also shows DUMMY_NV_ICC_SERIAL instead of the actual ICCID.
Same experience for me, I've been trying to find a workaround for over a month with no success. Alternative text messaging apps seem to work, but I don't trust 3rd parties with my SMS.
Unable to send SMS
Mike.
Which third party SMS app are you getting to work? Besides Google voice I have had no luck with any third party app?
I'm having the same issue. I'm on Resurrection ROM which is based on Lineage. Since update I can't send SMS at all other than via Google Voice. I can receive SMS and I can send/receive MMS.
I did find that if I change to 3g only for my network settings, I can send SMS. But then of course I don't get LTE data speeds for everything else. So the issue for me at least is tied specifically to LTE. Wondering if there is an APN or other setting I can change that would fix this but so far no luck finding anything.
Bug reported since 01/28
https://jira.lineageos.org/browse/BUGBASH-37
I've run into the same problem or similar. If I set my preferred network type to GLOBAL then I can send and receive SMS/MMS messages but I'm forced to either Roaming LTE or 3G. It's often stuck in 3G after a drive for any distance. If I force it to LTE, then SMS/MMS stops working and I can't place or receive calls either but the network will show up as LTE and Sprint.
To get there from Settings Home -> More (under Wireless and Networks) -> Cellular networks -> Preferred network type -> Choose Global.
Sometimes I can force it back to LTE but roaming if I switch temporarily to LTE then once it connects switch back to Global. Occasionally I have to put it in airplane mode to get the radios to reset and connect but some combo of switching network type and ending up in global and switching into and back from airplane will do the trick.
YMMV of course.
one way I fix it temporarily is to:
cell networks - carrier settings, let it crash
go in again and let it find your carrier
once connected, make a phone call at least to get it ringing
I can then make sms mms.
it's a rediculous work around but it works for me every time
SMS Sending Problem with Lineage 14.1 (31.07.2017)
Heyy
I'm not able to send sms from SIM 1 but can send sms from SIM 2 in Lenovo A6020a46 (2GB) on Lineage 14.1 (31.07.2017).
The same SIM is working good in another roms and Calling + Internet are working properly.
After dialing *#*#4636#*#* in Phone Information - SMSC Refresh then it appeared "Phone no.", 456 and I pressed Update.
But there was no process for saving or updating. Then I reentered in Phone Information but SMSC Shows blank.
What to do??? anybody help in this matter will be immensely appreciated.

I made this file using Odin with the steps from here. I flashed the file, set the connection to LTE aand it worked. https://forum.xda-developers.com/showpost.php?p=71582847&postcount=5908
To fix this issue with having LTE signal and sending SMS at the same time you have to open EnginneringMode app (or *#*#3646663#*#*) and check 'Sms over Sgs support' in Misc Feature Config tab.
Doesn't work because nothing comes up entering the code. Any idea?

If that code doesn't work for you, try to find an app called Engineering Mode MTK. Unfortunately I cannot attach any screenshots yet (I got less than 10 posts).
fix
there is an option in network settings (enhanced 4G LTE mode for comunications etc) i disabled that option and messaging works fine now. before unchecking this option i could only send sms only with phone on 3g mode, now it works fine. i think this option is for hd voice calls via 4g lte.
I see this is an old problem and I´m having the same problem. I can receive SMS, but I can´t send.
But to add to that, I couldn´t connect at all with my previous carrier and changed carrier after which I can use data, call and send SMS. I still can´t receive SMS.
Loving my Urbane 2nd Edition since I got it and upgraded to AW2.0. However, noticed that the watch doesnt "kick" into LTE mode as well as it should at times when I am out of range of my phone's BT or home WIFI. Works better when rebooted. Anyone else having a similar issue where the watch almost refuses to automatically switch to LTE without the phone BT or WIFI?
Mine had never got cellular connection worked, the LTE and wireless signal are showing, but the little cloud with slash is displaying too, never got real connection, no matter if the phone is on/off or in/out of range.
Since 2.0 only calls are available via LTE, but no data streaming
I tried several times with/without roaming, choosing carrier or auto, I can't receive data via the sim card of the watch. Can you please approve or i have a sim issue /watch issue?
If you're using an MVNO's SIM that requires special APN settings, it won't work. Forget about using FreedomPop or Straight Talk or such - it'll have to be the MNO's own brand or APN settings to work. There is no APN editor in Android Wear / WearOS.
Found out the guy lied. So the US unlocked N20U does work with VZW wifi calling.
It definitely does work with my N20U on Verizon.
The only differences between the Unlocked and VZW version are:
1. Native Verizon video calling doesn't work on unlocked, but the integrated Duo video calling is better anyways.
2. Verizon's model doesn't have the Samsung "Smart Call" feature for Caller ID. Instead, it uses Verizon's app.
3. Verizon's version has the Verizon bootscreen and a ton of bloatware, especially games, news apps, and what not. Fortunately, most can be uninstalled, and the rest can be disabled using ADB.

I can confirm all of the above. I have an unlocked phone, on U1 firmware, with a Verizon SIM. Wifi calling works. There is no "Advanced Calling" menu in Connection Settings, but there's a toggle for VoLTE and it was switched on by default. No 4G icon, but rather a LTE+ icon is shown in status bar. The only thing I haven't found a workaround for is the native video calling. I cannot initiate it (phone app does not show the option when I'm on a call with another Verizon phone) and if another Verizon phone attempts to initiate a native video call, it tells them that I cannot accept video calls. I checked my VZW account settings on a PC, and despite the video call option being on and not blocked, native calling doesn't work, as described above. Duo works fine for video. I was able to get Visual Voicemail by installing the app that I go from another thread. I installed it before checking to see if the U1 firmware added it by default, so I can't say for sure that it wasn't there already.

So I had an interesting observation. I flashed my Verizon Note 10+ to U1 firmware and noticed a drastic reduction in data speeds. After getting the Note 20 Ultra, I noticed the data speeds were nearly doubled. I then disabled a ton of Verizon and Samsung apps, and my data speeds dropped drastically as well. Through the process of elimination, I found that the "My Verizon Services" app seems to have a major impact on data speeds. As long as I keep that enabled on the Verizon firmware, data speeds are blazing fast.
Is it possible that Verizon uses apps to prioritize or de-prioritize data speeds? I'd be curious if one could do a side by side of the Unlocked vs Verizon firmware.

Thanks for sharing your observations regarding wifi calling. How can one tell it is working? I am used to older phones advising that wifi calling was in use via text in the phone app. I'm not seeing this notification on my new unlocked T-Mobile-branded N20U with Verizon SIM.
I also noticed the VoLTE toggle in the phone app, switched on and greyed-out, can't be deselected. Of course they don't want to support anything but VoIP anymore. What is the behavior, if the cell signal is decent it won't use wifi? It can't be forced to prefer wifi, can it? I used the trick of putting it in airplane mode, then turn on wifi to try and force it to wifi call. It said it couldn't make the call in airplane mode, which is not encouraging regarding wifi calling being functional on this phone/provider combo.

From what I've found, if you put another carrier's SIM in a truly unlocked carrier branded phone, it should prompt you to apply your carrier settings upon boot. For example when I put a Spectrum SIM in a Verizon phone, it "converted" the CSC (Carrier settings and boot logo) to Spectrum.
My recommendation is to attempt to get the SIM to switch the CSC automatically. If not, use the patched ODIN to flash the Unlocked U1 firmware, and optionally you can flash Verizon from there if Verizon's Video Calling is a must.

Thanks for the detailed response. I was a little concerned about the T-Mobile branding, and what that truly meant at the software level. I installed the Verizon SIM to this factory-reset phone. If it was going to switch CSC I think it would have happened then. It went through the usual setup steps, but still displays T-Mobile screen at boot. I'm not sure what else I would do to "get the SIM to switch the CSC automatically".
Would you agree with my conclusion that wifi calling isn't working based on the outgoing call failure when in airplane mode with wifi on?
If there is better, more-unlocked firmware I'm not opposed to flashing it. It's been a while since I've played with rooting and custom ROMS, but I'm guessing stock firmware is a lower-risk activity on an expensive phone.
I'll refer to this link to try and flash to unlocked U1 firmware, hopefully that will allow wifi calling compatibility:
OTA and Non-OTA Firmware for N986U and N986U1
Hey guys, really hoping someone is able to help me.
Back in September 2020 I purchased the SM-N9860 variant from T-Dimension for use in the UK on EE's network. Everything has been running smoothly since day one, up until yesterday (31st May) where the phone would constantly struggle for signal, flip flopping between "No service" or extremely slow 4g. If I try to make a call I get the "Not registered on Network" error message.
Since then I have done everything I can think of:
- Restarted the phone several times
- Switched Airplane mode on/off
- Manually selected my carrier
- Reset network settings
- Tried my sim in another phone (which worked fine), and tried a different sim in my Note 20 (exhibited the same behaviour of "No service")
- Checked IMEI but it's not been blacklisted
- Tried my sim in the SIM2 slot
- Full factory reset
but none of them made a difference.
Tonight I decided to try and flash different firmware to see if that might have any effect; both TGY and BRI firmwares were flashed successfully with Odin but neither have solved the problem. I'm now at the point where in my home I can see the 4g symbol appear above the network status for 30s - 1min but it never actually loads any data, before returning to "No service". Compared to my fiancee's S10+ which is also on the EE network and easily hits 20Mbps without worry in the exact same room.
Does anyone have any suggestions of what to try next? Has anyone else encountered this?
Thanks,
RBrNx
I've spent some more time investigating this and I am 99% sure it's an issue with the device.
Below you can see a screen recording of the issue that I made this morning while I was out a walk, you can see it goes from having signal but no internet ("Emergency calls only"), to "No service", then to 4g but I wasn't able to even load a website, before it moved back to "No service".
I've also attached two screenshots from the NetMonster app, one is from my Note 20 and the other is from my fiancee's S10+. Both were side by side when the screenshots were taken - mine has no service and her's has 4g.
I've since tried a number of other SIM cards in my phone, including another EE SIM and a Three SIM - both work immediately in the S10+, but neither are able to register when put into the Note 20.
I tried to contact Samsung Support but they were next to useless. The UK support team told me I'd need to contact Hong Kong support "as they have full access and information", but all the HK support could do was tell me to visit the HK Support Center...
I'd love to be able to fix this issue but I'm not sure what else to try
EDIT:
Some more information that I forgot to add - When I am out of the house I can occasionally receive calls/texts or use the internet, so I know for sure that they are all working (i.e EE haven't blocked my account) but most of the time I am stuck with "Not registered on network"
I'm wondering if it's an issue with the antennas, it's almost as if they are somehow weaker or less receptive than they were a few days ago
Does it behave this way when in safe mode ? How about in 3G mode? If it's hardware then Samsung doesn't recognize devices that are from other regions in relation to warranty work. You'll have to test the after sales support of T Dimensions now. Failing that sell it as is on eBay for parts or try and trade it for another device.
I'm using the same device on Vodafone UK and no issues here at all
I'm using an N9860 HK model, also from T-dimension, with EE since last autumn. I have not had any such problems with mine.
I haven't flashed or rooted the phone, but I have tinkered in the service menus in order to gain 5G service and possibly other service improvements.
Yeah, same for me. Changed the 5g whitelist settings but no root.
