I bought my One S from Telus through a friend who's a Telus customer this past June and used an unlock code bought online to use it with my carrier (MTS). After setting it up with the MTS APN settings it worked perfectly for several months. Then around 2 or so months ago, I got an OTA update to 4.0.3 and as soon as I got the update, the phone started regularly dropping the connection to the network. Signal strength wasn't an issue, it would just cut out completely, giving the message about emergency service only. Some days it wouldn't be too bad and would just cut out momentarily and sometimes it would drop for a good time or drop so repeatedly as to make the phone unable to even dial out. It would sometimes even vary in severity throughout the day. I haven't rooted or unlocked the phone in any way except for a carrier unlock code.
As I was very busy with school, I gritted my teeth and beared it but it seemed to get progressively worse to the point where I finally sat down to seriously look into, and got on the phone with MTS tech support, HTC tech support, as well as trying to talk to MTS sales reps at their store locations. MTS is clueless on what to do (or just refuses to help) because they don't sell the One S. I talked to HTC three times and their only solution was to see what happens with sim cards from different phones and they also noted that the stock software, as well as updates, are tied to the carrier and could be causing problems.
MTS also talked me into buying a new sim card and seeing if that fixes the issue, where it actually made things worse somehow and now the phone often cannot get a connection at all or drops it and doesnt pick it back up (on the settings screen, "mobile data" gets stuck at "turning on" but even voice doesn't work). I've tried getting other people's sims to try in my phone but they all seem to have ones of different sizes. All I've been able to try is a Rogers sim (which I only could test for a short time, but seemed to stay connected and stable for that time) and a Telus sim (which wouldn't work at all, strangely enough. Though one person I talked to at HTC said that by unlocking my phone its possible I received the OTA update from a different carrier such as Rogers).
I'm not sure what to do here as I've tried messing with many settings and searching for solutions without finding one that works. One of the HTC reps I talked to said that I could either send it in (and lose the phone for 2-3 weeks without a guarantee this wouldn't happen again) or while they can't recommend it, I could try rooting the phone and downgrading the software to what it was before. A guy I talked to at a local cell repair shop listened to my problem for about a minute and a half and then said rooting would fix it.
If anyone has any suggestions, I would greatly appreciate hearing them. I'd like to get some more input before I void the warranty by trying to root it and replace the software with some in case that doesn't fix it and I have to send it into HTC for a big fee.
I bought this phone off Ebay about 3 weeks ago. It was labeled as a d820 The listing said for parts does not read sim card but everything else worked. Being Semi decent in the tinkering world I thought I would spend the 40 $ on the phone to see if I could make it work. When I got the phone it was on the setup screen because it was just factory reset. When I put my sim in (T-mobile) it showed that it had a signal. As soon as finished setup it lost the signal and could not connect again. So obviously it is some kind of software issue. So the first thing I did was try to update it from lollipop to marshmallow. Once again it showed it was connected to my network until completing setup. This time when I was in the bootloader I noticed that it said it was a d821. I figured well I paid 40 dollars I was probably going to get ripped off somewhere. So then I started reading about how to use the d821 in America thinnking that was the issue. I tried the qpst thing where you add the additional bands- nothing. Then I messed around a bunch in the cdma tool after reading a thread about adding cdma to the device. I also tried flashing various modems and roms with no luck. Last night I thought maybe theres something I missed hardware wise in the phone so I opened it up. I checked all of the connections and everything was fine. I started reading the numbers and got really confused. On the back of the phone it says d821 under the lg logo. but on the inside of the back cover and the plastic shroud on the motherboard it says d820. This might be irrelevant but it would be super great if someone had an idea of how I can get this to work on T-mobile in the USA because with a decent rom this phone is wayyy smoother and faster than my 5.5" alcatel idol 3 network unlocked from cricket (So lte sucks). All i want is a phone that has a stable lte connection XD
ANY ideas how to fix my D821?
The model # in the bootloader is the correct model #. Is it possible the imei has been blacklisted?
On the motherboard, near battery connector there is info about 32/16gb and d820/d821.
I've been using Vodafone Pay as my primary method for some time now but sadly they have decided to shut down the service. It seems these mobile network operated NFC payment services aren't making any money as EE shut down Pay on Tap a few years back.
My question is there any real alternative? Android pay requires my phone to be switched on and unlocked - two features which are sadly a luxury my old LG G4 can't handle at the end of a busy day without a charger. Vodafone pay was great in that it used the SIM card and NFC chip to make payments so it could be used when my phone was switched off as well.
Is there any service/app that offers this as well? I haven't managed to find anything so far.
TIA
9 months ago I switched providers from NTT docomo (where I still used a SIM lock free iPhone) to SoftBank (where I got a new Pixel 3, and first time in many years that I got a phone + SIM).
But like how the whole nature of planned obsolence works, gradually going from best phone ever to falling apart to boiling my blood.
First the USB-C port of my phone stopped working (so I am now forced to use wireless charging and SFTP on a local network), then the FeliCa chip started becoming instable (which is fine, I can still switch back to a dedicated SUICA card where the FeliCa chip works for a decade), then I was forced to set up a finger print to use Google services (later on turned out to be just a policy issue in Google Apps, I already fixed that) which only makes my phone more insecure (random unlocking if accidentally unlocking the phone within 5 seconds or when the scanner touches the skin of my lag through my pants), but after I turned off finger print authentication my phone started to randomly unlock itself whenever I get extreme weather warnings (and since it's summer, I'm getting multiple times every day).
So I was looking for switching to another phone, and I bought a SoftBank branded Digno flip phone from Amazon, and my SIM card didn't work.
I went to SoftBank have them take a look, the guy was searching using my IMEI for 30 minutes only to tell me that the Digno problem is a very rare case and that Aquos flip phone doesn't have this problem because Digno is too old (released before 2015).
So I bought the Aquos flip phone that he recommended me, but again my SIM card didn't work.
I started to question it, and put my SIM card into my SIM free iPhone: didn't work.
Then I put it in an Aquos smartphone which I bought specifically as a SIM free phone: didn't work.
I went to SoftBank again (this time to a different store because I didn't have much time) and explained the situation.
The guy then told me that I must have my phone registered at SoftBank for the SIM to work.
Then I asked how I can do that, he said that I must purchase a phone via SoftBank instead of Amazon, or otherwise let a totally different SIM card get issued.
By this I'm not complaining or asking to hack the system, I only want to ask if anyone knows about such a tactic? Did anyone experience it too (in Japan or overseas)? And is it normal for a phone provider to lock your SIM card to a specific phone?
And while we're at it: if I flash my phone with a custom ROM, will this render my phone to be unusable with this SIM card as well?
Looks like you are down with a string of strange events and bad luck.
Softbank seems to be a d*ck and I would change a provider if I am you. It is illegal in my country, malaysia, to lock devices to network. But you can easily just register your phone imei to Softbank if you really like the coverage they provide.
As for phones I can't comment on that as I never used pixel, aquos or any of the phones you mentioned but the fingerprint able to unlock by touching your legs through your pants sounds like a hardware failure and I would bring the phone in for repair.

In my experience Docomo works really well within the Yamanote area of Tokyo, but I cannot afford living there and my work is just outside of that area.
And I already had home internet from SoftBank, which were the 2 reasons why I went with SoftBank, plus its coverage works really well (even when I go to a mountain village north from Sapporo, which I did yesterday, I still have really good coverage).
Their SIM only plans were also really good, I really feel like an idiot that I took a SIM + phone set this time…
My friends (I have them despite my username) also recommended me to go with au, but I didn't like what they covered (can't remember what exactly, but I remember it was somewhere among those lines).
But would be nice if our politicians would make this illegal too, once big companies obtain too much power, it's never going to be enough for them.
Edit:
I only want to add that the only time I had a bad coverage with SoftBank was when watching fireworks at the Edo river, but I'm not sure whether it's because I was near a big river or because the part of the river has a 3 point prefectural border (between Tokyo, Chiba, and Saitama).

It isn't a matter of "locking the device to the SIM", it is a matter of the device being registered on the service providers network using the device's IMEI number and the SIM card number being registered as being used with that device, both of these numbers must be registered together in your service account, that is how the network recognizes your device and how it knows to send service via that SIM to your device. When you switch to another device, the new device must be registered on the network and the SIM must be registered as being used with that device.
It's similar to registering your car and registering a license plate on that car. The car is registered to identify it as your car and the license plate is registered to identify that the license plate is for your car and not someone else's.

If it's true, then I'll try it out.
Somehow confusing if employees of the same ISP working at different branch stores tell me totally different things. (´；ω；｀)
So I have a Z Fold 2 I bought on ebay. I believe its a Verizon device however the model number is SM-F916U1, and I know Verizon unlocks their devices after 60 days. I've had the phone for about 45 days now. Well whenever I try to use my cricket sim card in it it will register on the network just fine and everything works for about 10 to 15 minutes and then it kicks me off the network and locks it up. Do I need to get my phone unlocked or is there something I'm overlooking? Can someone point me in the right direction I've been Googling the hell out of this and can't find an answer.
I would guess it's a stolen z fold did u check the imei? When I bought my z fold 2, i got an empty box from ups. Had to file a police report and everything. I didn't buy from ebay but best buys. I never had a ups package stolen until this phone so if I were to guess the one u bought off ebay might not be good.
Yes that was the first thing I did its not stolen and jts fully paid off.
I'm completely wrong then. Sorry I'm not sure possibly 60 day thing like u said. Can u try a different sims?
Yeah I've tried different sims and they all work except after 15 to 20 minutes it suddenly kicks me off the networks and says network locked. When I first got the phone I put a Verizon postpaid sim into it hoping it would somehow help but idk. The problem here is I don't know when this phone was originally purchased or if it was ever activated on Verizon before I got it in my hands. Is there any way to maybe find that info out?
Most likely you'd need to contact Verizon to get them to unlock it on their end, however since you weren't the original owner, they might refuse to do it.
I did contact them and they said on their end the phone shows as unlocked.
