Appreciate your thoughts on whether this is hardware issue.
I'm in London UK, had phone for 6 months, worked flawlessly. Until last week.
Currently, I get full bars of 4G+ everywhere I go, and data works as it should, 140mbps + speed
I never had voice over 4G, so everytime I get a phone call, the phone drops to 3G for the call, worked fine too.
For the last week, the phone is unable to pick up a 3G signal. Anywhere, so it's not a network coverage issue. If I go into network settings and change from 2G/3G/4G auto to '3G only' i get no service, and 'emergency calls only'.
So I can't make or receive any calls, unless I use Skype or something over 4G.
What I have tried so far:
1. Reboot phone
2. Remove and clean SIM card
3. Factory reset phone
4. Got a replacement SIM from the Vodafone store
Still the same. I tried the new SIM in my work phone (iPhone 6) and it works fine, full bars of 3G & 4G available.
Do I have to send the phone for repair?
Seems like you need a repair, speak to Samsung they are usually pretty good.

Hey, I'm having this weird problem with my 3G connection/data connection. If I end up loosing a 3G connection during a call. The only way to get it back is to end the conversation. To further explain... If I hit a spot with no 3G, then go back in a 3G spot, it won't come back on. I still have a good signal and i can talk but there's no E, G or 3G showing. While my phone is in this state I'm unable to browse the web,, it says no data connection which is odd because i obviously have a connection if I'm on the phone...3G starts to come back on As soon as i press end call. It instantaneously goes to E, then G, then 3G. At that point if I make another call, I'll still have a 3G connection and my phone works fine, i.e. i can browse the web and talk as usual. If I hit a spot where I loose 3G again (while in a call) it won't reactivate, I can continue to talk but I can't browse the web. No E, G or 3G showing (just bars with good signal) and it won't go back to normal until I end the call. Any suggestions?, thanks. unlocked bootloader, completely stock, not rooted running 2.3.3
Its an issue but not an isolated issue. I've experienced this as well, on both T-Mobile and att phones. Maybe LTE technology will help with better signal transfer than 3g.

Same thing here.
Just for the heck of it I called t-mobile to get my original sim card activated. It's an oldie from 2004. They said it should be turned on within the next 24 hours. I don't ever remember it happening with any of my other phones while using the older sim. Maybe there's a connection,, it's worth a try, I don't have anything to loose. I'll post my results.
i was under the impression that you can't surf the web and make a call at the same time. since day 1 my phone has always turned data connectivity off as soon as i make a phone call. i thought its supposed to be that way lol. it isnt?
EDIT:
just did some testing. on 3G i can make phone calls and surf the web. on E, i cannot. i leave edge on all the time to save battery (dont need 3g to check emails), so i guess i thought its normal for data to cut out haha.
tmobile and ATT networks are not setup right now to hand a call from GSM back over to 3G during a call. if you are on 3G during a call, and lose 3g and go back to gsm, you will stay on gsm until the call ends. then the phone will switch back to 3g.
this is done on purpose by ATT and tmobile, the thought is that they will enable this hand off direction once 3g is widely covered. but since gsm footprint is larger than 3g, they set it up this way. its annoying, but normal.

You missed the hoop with this one lol. Topic is not about this.

Roger P, I'd hit thanks for your answer but I don't see the thanks button to click. For me it's a huge deal to have some closure on the matter. As we all know, it sucks when you loose confidence in your phone. Don't know if it's a web site etiquette thing and that's why I'm not seeing it. Either way, thanks a lot. peace
It depends on the 3G carrier setup by your operator. For example, my operator uses 2 carriers for 3G service, one is data only carrier and the other one is shared between voice and data. So sometimes 3G data connectivity goes away during a call because I was connected to a data only carrier and sometimes I keep using the data connection during the call because I was using a shared carrier. I don't know if this is the case for T mobile.
Please help
My S2 plus loses signal, data and no able to call and eferything. After restart ok for couple hours and then again. What can I do?please respond.
Reset to your phone..if that doesn't do the job ,just flash new firmware. If still doesn't work,send back to service center
I would recommend you send to service center.
On second thought,better check whats wrong with ur sim card.i think the problem start from there.pull it out and clean the contact point a bit,or switch other sim
Yeah, it can be the fw. After I had my motherboard replaced it wasn't picking up any signal at all. got at a friends place on the 9th floor to see that it caught 1 operator out of the main ones. Thought they didn't plug the antenna or something, send it back in only to receive it reflashed and nothing else.(the repair course stated something like: no damage fount, reseted settings). Guessing they just flashed England's FW and the bands didn't work well.
I had something like this when i had gsm/wcdma connection type (dunno how to it right in english). Where i live there is poor 3g connection and sometimes when phone loses 3g connection and should switch to 2g it does not and simply says no signal. I switched to gsm only for a while (should get better area coverage later) and i don't lose my signal anymore. If it is crucial to have 3g you can switch on and off airplane mode and you signal will be back, at least it was for me.
I have the opposite of the LTE dropping problem I see most people have. I can't get 3G, but my LTE works fine (well, once it spazzed out after a PRL update and would only do 0.5mbs on LTE). At work, where I know I can't get LTE, but could get 3G with my Note 2 (and we even have a repeater), I can't get data. If I go to the window where I can barely get LTE and reset my antenna, it'll get LTE, and when I walk away it'll flash 3G for a second and go out. I still get several bars and can talk and text fine. Everyone else with 3G is fine. After thinking about it I realized that in the month I've had the phone I've NEVER been able to connect to 3G in places where I used to be able to. It's LTE or nothing. I'd be more than happy with 3G if the alternative is to read a book. Could this be a SIM card issue? Hardware? Firmware? It's annoying the hell out of me, I work 10 hour shifts at night, I need my data.
Just a follow up, I downloaded a network signal info app and it shows me having a solid 40% signal. Net type: will alternate between EHRPD, EVDO A, 1xRTT, and Unknown. Data state: will alternate between "Setting up data connection" and "no activity". It seems like it's looking for a connection but won't connect. I know the signal is there. The only time I can get the 3G logo to light up is right after going out of LTE range, it'll light up 3G for a few seconds and then go out. My coworkers with Sprint have confirmed the new repeaters we have are working, and I've confirmed it won't hook up to 3G at home like my old phone.
Hi i have a nexus 5 android 6.0.1 and whenever I make or receive a call the network drops from LTE to 3G to Edge. It stays on Edge even after the call has been ended and the only way to goes back to LTE is when the phone is locked for a few minutes. I checked the settings number cellular networks -> preferred network type and its on LTE. I have done a complete wipe on the phone twice and still the same issue.
Also in the past I have another issue which was resolved and I have had this phone for about 2.5 years and after the first 6months the sim was unreadable. The person I got it fixed from stated that the guy I bought the phone off reported it stolen and the only to use it was to switch the motherboard. Im not sure if they are related .
The main issue the network dropping down to Edge is causing is when I drive for uber and passengers call me sometimes I cannot start the trip or load the gps for a few minutes .
This is because of CSFB functionality. LTE is used only for data connection and if you receive or place a CS voice call, then the phone switch to 3G or 2G (depends from signal strenght) to make a call and after that if signal is strong enough switch back to LTE.
I bought an extra phone cheap (H990N) - was warned that there were problems with the reception. I bought it from France, and live in Denmark. The problem seems to be that it has difficulties shifting between 4g and UMTS, that I use for calling on my working phone. It gets stuck, and will not work with data/ calls. The signal is stronger than my well functioning H990DS (using same sim card), and it can now and then make a phone call, and now and then get data. I have been in the *#*#4636#*#* menu, and played with the settings.
My working phone (H990DS) has the LTE/UMTS (PRL) setting, which shifts between LTE in data, and UMTS in calling without any troubles. In the new unstable phone I have seen both working in the new (H990N) phone, but it does not shift, and after shifting between data/ calling it stops working until I restart in the ping test menu. As far as I can see, the Hong Kong model should have all the relevant frequencies, but it gets stuck. I can mostly get a stable LTE if I choose LTE only. That works fine for data, but I cannot use that for calling.
The phone is in a very good physically condition, and everything else works fine - GPS, wifi, apart from problems with connecting.
I have LGUP'ed it to newest Oreo, and also inspected the contacts at bottom plastic thing with the antenna and the motherboard. Everything looks fine, and as mentioned, the measured reception in the hidden menu is even better than in my working phone.
I assume that the fault is either some firmware issues -but it sustained when updating from Nougat to Oreo, which gave me acces to the secret menu.
Is there anything else I can try, apart from putting it away as spare parts, or buy another motherboard?
