Unlocked Sony Arc Hotspot not working

Hey there everyone
first time post on this forum. Hopefully someone can give me some good news on how to fix my problem.
I am on the Fido network in Vancouver, BC. I recently bought a Sony Arc from Rogers and had it unlocked. Everything on the phone works great, but I cannot get my mobile hotspot to work. Wifi, GPS, email, etc. all work fine.
I had read somewhere that I might have to change my APN settings, but when I did that, flash turned off on my web browser - maybe I had put in the wrong setting.
Then I also read that you have to change your WAP settings, but I don't know where to find that.
Hopefully someone here can give me some good news on how to fix this bug. I did phone both Fido and Rogers and they said that it should work and that nothing is blocked on my account.
Would really appreciate some feedback and some help with thanks. Thanks in advance.

Nothing to do with you're APN's etc if that' not working... if you're getting a data connection (GPRS/ 3G/ HSDPA) then this should work fine...
if it's not then suggest trying to reflash the firmware using SEUS or Flashtool.

Weird. Most of that doesn't make sense. Adobe Flash is unaffected by APN settings. Unlocking has nothing to do with 3G either.
A quick Google search turns up:
APN Settings for Fido: http://forums.fido.ca/t5/forums/forumtopicpage/board-id/Smartphones/thread-id/768/page/1
Like im_iceman said, if 3G works, hotspot should also.
Have you set the password? SSID? etc.?
Hotspot works fine on my arc. And X10.

Portable Hotspot Doesn't Work For Me Either
I purchased an Xperia ARC from Mobicity in Australia. In order to work on the NextG 850 MHz network I purchased the Model LT15a which is described at dudubdub.xperiablog.net/2011/04/17/xperia-arc-lt15a-sold-on-ebay/ (replace dubdubdub with www). This is built for and branded Rogers. If I switch on Portable Wi-Fi hotspot it works so that I can connect my laptop to it but turns off my data connection so it is useless. If I turn the hotspot off the data connection comes back on. I can't have the data connection and the wi-fi hotspot on at the same time.
I've interpreted this as a Rogers special build that doesn't allow tethering to satisfy Rogers commercial requirements. Telcos in Australia don't mind tethering but some others do and I guess Rogers is one of them. Its a guess though because I don't know Rogers policies.

Sounds like Rogers have added some power saving app, and this is automatically disabling your data connection when WiFi is on (JuiceDefender does this I think, but might be intelligent enough to notice when you're using the phone as a hotspot - I've not tried yet).
If that's the case, you'll either need to track down the app and remove it (there's a guide on here somewhere for removing pre-installed system apps) or flash your phone with more generic firmware that doesn't have it.

[Q] Unable to receive receive calls while mobile data is on

I am going nuts here I have been searching all over the net and I still have not been able to fix this problem, so I am sorry if this seems like a repeated thread.
I have a Tmobile rooted Samsung Galaxy S III, I was running a nightly Cyanogenmod 10 ROM. Yesterday there was an update for that rom and I downloaded it and installed it, everything was fine and running smoothly until some people started telling me that they were not able to reach me by phone. I tried checking what was wrong and I finally realized that whenever I have my mobile data on or while I am using it I don't receive voice calls. I tried looking everywhere for a way to fix this and I came across the ##DATA# code in which I could turn off the DDTM option but unfortunately my phone doesn't recognize that code.

}
this is the message I get every time I try to enter ##3282# code.
I thought that maybe something was wrong with the ROM itself so i decided to browse around here for one for my Tmobile samsung galaxy S 3 and I decided to install this one [ROM][4.2.2][RC1] LiquidSmooth ROMs - d2tmo - 2|14|13
after wiping data/cache and dalvik cache I installed this ROM and this is my current phone info
and still when I am using my mobile data I cant receive calls nor put the ##DATA# code to turn off DDTM.
is there any other way I could access that DDTM option? I am so frustrated or maybe I am doing something wrong.. I do admit I am no pro at this.
it seems that no matter what ROM I use that option to send calls to voicemail while on mobile data is stuck!!!
I tried downloading the stock ROM from Tmobile and flash it with Odin but every time I tried to do this the process would be stuck at aboot.mbn.
This is driving me crazy, everything works fine on my phone except for that, I cant receive calls if I use my internet, I am afraid of using it because I might lose some important calls.
Please if any of you could help me I will be greatly appreciated. Thanks in advance

Weird. Try updating your modem to LJC.

I've never had this problem with my phone until now. I would be browsing the net and get an incoming call, now my phone never rings unless the internet is off. It is annoying and I cant find a good fix for this, I am going insane,

Check your IMEI. You can use cell data and phone calls on GSM which is T-Mobile, only HSPA though, not on edge. You cannot on CDMA like Verizon on any cell network. I say check your IMEI cause you might only have edge network due to the loss of your IMEI while flashing.

[Q] Verizon HTC ONE can't add new APN

hi, I have verizon htc one running on stock 4.4.3, sense 6.0. I want to use it in europe on gsm network, voice and text works perfectly, but I can not use data because I can't add new APN. there is not options to add new one in access point names. when press on three dots just comes up "reset to default". so what should I do now?

I would call vzw to unlock your SIM, then plug in a prepaid SIM from a local European carrier.

I have this same issue. I was already overseas, and couldn't add or edit the APN I needed to use for O2.
I've called Verizon multiple times and they say "it's already unlocked" over and over again.
Is there anybody out there with a Verizon HTC One and is able to edit the APN data? If so, what did you do to get the phone to allow you to do that?

same here. using a Verizon HTC One (M7) on Rogers network in Canada. i cannot edit the existing APN or add a new one at all. i am connected to the internet, but it shows an 'E' instead of '4G', and it's very slow. any work arounds?
also, when i try changing Network Preferences and adding Rogers' MNC, (302720), it tells me my Network Preferences list is full and won't save anything when, in fact, it's actually completely empty! any ideas?

Does Rogers use LTE band 13? If not, you will not get 4G. As for HSPA/3G for GSM, the phone only has 900 and 2100 mhz for it. So if your carrier doesn't support those frequencies, you are stuck on edge (E).
http://www.htc.com/us/smartphones/htc-one-m7/
Specs tab shows the frequencies I discussed that the phone can support.
Edit: I also put this info on our Q&A thread.
[SIZE=+1]Q2: can I SIM unlock this phone for other carriers?[/SIZE]
The m7wlv comes SIM unlocked out of the box. It only works on certain frequencies. See if your carrier supports the below frequencies.
CDMA: 800/1900MHZ,
UMTS/HSPA: 900/2100MHz,
GSM/GPRS/EDGE: 850/900/1800/1900MHz,
LTE: 700MHz (Band 13)(only Verizon uses this LTE band thus far)​

Did you go to network preferences and click add....then click operator list. Scroll down the monster list and add Rogers wireless? Once you add it you need to reboot for the apns to autopopulate. With the new way of doing it they autopopulate.

Screenshot?

here (as you can see, the list is empty, but it's telling me that it's full!):
and when i add Rogers Wireless by entering the MCC / MNC manually, i'll get this:
and going back to the previous page gives this message:
also, i cannot edit or add any APNs at all.
i'm sure it's the phone. is it SIM locked? (it shouldn't be given that it's from Verizon, but i got it as a replacement from Verizon because my first one had a faulty GPS, and it was refurbished.)
any ideas?

When you click add.. don't click add network code. Click operator list.

i didn't click on anything. that's the window that pops up when i go t Network Preferences List. i cannot do anything else.
i really think it's a phone software issue (the same phone, using a Verizon SIM card, was able to connect to Rogers' 3G network while roaming)...something must have messed up the software. funny thing is that with the Verizon SIM card, i could look at the operator list and add/edit the APN and all that.
is there any way, short of a factory reset, to revert the settings back? could it be that the phone is really SIM locked?

Having the exact same problem
I'm having the exact same problems as those described above... I am on a fully stock Verizon M7 with the latest official release. Not rooted.
- cannot add new apn.... Option missing from he apn menu
- when i attempt to edit the existing apn, all i can do is edit one line... The apn itself. All other lines are grey and will not allow me to change the settings.
- with a non Verizon sim in the phone i was also having the " network list full" errors described above...
I was in Europe with Lebara mobile sim and was able to get on 3g but it was unstable as apn settings were incorrect and not editable. I was in the UK on a 3 mobile sim and all was the same. Now back in the US, the same problems above with apn add/edit are still there though my "available networks" settings are behaving normally with the Verizon sim in there.
IT must be something wacky with this build or Sense 6 as my GF is also on Verizon and her Razr Maxx had none of the above problems as she travelled with me with the same carrier sim cards as i was using.

yeah, it's very annoying. maybe we should contact Verizon to figure out what's going on.

I have an HTC One with the exact same problem. It won't let me put in the proper settings to activate mobile data on the Mexican Telcel network. It was a Verizon phone which is unlocked and will do voice and text but since the APN settings are not allowed to be edited it is not data capable. I'm in Mexico for a few months and this is ridiculous. According to Verizon "of course your phone is unlocked. We haven't sold locked phones in years." I guess they aren't locked now they are disabled or crippled when you try to take them to other networks. BTW this isn't just a problem of us not knowing how to input APNs, this is the problem of the phone not allowing editing at all. Very, very frustrating. Especially when you find out that root is almost impossible when it has the latest over the air update.

Factory Reset Doex Not Fix This
Confirming that factory reset does not fix this. So don't waste your time... Ih yeah, and HTC backup and restore service is down until further notice... Another fun surprise

Maybe I'm wrong but I thought you needed to be boot loader unlocked and s off to edit the apn and mcc list since they are system level files. You need read/write ability for the system in order to do that which requires root.

nevermind

^ what does this "nevermind" refer to?

N910V No signal in Argentina

Hello everyone,
I bought a Unlocked Note 4 from Verizon in USA. In Argentina I don't have signal. We use GSM so it should work right. I know this device has not root access. I just want to make some calls or messages.
It doesn't let me search network manually. It throws an error "error searching networks"
Android Version: 4.4.4
Network Mode: Global/GSM
Somebody could help me on this.
Thanks in advance.

I am in Europe past month, leaving to us in few days and was using my note4 in GSM mode all the time and switching between carriers on a prepaid sim. I would do factory reset or maybe get a new sim.
My prepaid sim allows roaming on all carriers.

Did you use others GSM carriers instead of T-Mobile?

Which carrier are you using this on? Verizon has always used CDMA for 3G, not GSM. The Verizon Note 4 (SM-N910V) does seem to have limited GSM support, but it might not work on every GSM carrier.
This website seems to be pretty accurate: http://www.willmyphonework.net/

Acording to that page my phone should work perfectly
with 2G, 3G, 4G LTE.
I'm using:
Brand: Samsung
Model: SM-N910V
Country:Argentina
Carrier:Claro Argentina
I don't know what is the problem.:crying:

You may need to add new APN settings before it will work.
On mine, the option to add a new APN is disabled, but I'm actually using mine on Verizon with a Verizon SIM card, so I'd have no reason to edit the APN settings manually. Are you able to edit yours?

I already set the APN and nothing happens. I'm not sure APN could be the problem. Should be something else.

If the APN settings aren't correct, it could absolutely be the problem. It's worth double checking.

APNs
I tried with severals APN and nothing happens.

I have an Oneplus One with the same APN and works perfectly. That's why I think the APNs are not causing the problems of signal. I still having no signal. I cant make neither a call nor send a message.

Hmm sorry bro not sure what is going on.. last thing I could suggest if you have some money to spare try any other sim card from different provider or ask a friend to swap it for a minute or two,anything to test that it's not your carrier somehow not wanting to work with VZW N4.

Hey I read something couple days ago and forgot to get back at you.. I read somewhere if you block activation agent it should work some people on T-Mobile USA had the same issue. Use debloater to block activation agent on boot. They said this could be because the note could never been activated on Verizon even for 30 seconds and this is why it might be happening.
So block activation agent,and setup wizard so it's blocked on EACH BOOT.
Let me know

US991 Unlocked - VoLTE or Simultaneous Voice & Data

Hi all,
I picked up an unlocked LG G4 US991 from Buydig via eBay the other day. I got the phone today and was on a call and needed to use data and realized that data did not work. I currently have a Verizon sim that I noticed it did not work on . I also have a T-Mobile sim. Is it possible to enable or use VoLTE or Simultaneous Voice & Data on the US991 with Verizon service or T-Mobile service?
I don't have the T-Mobile sim right now to test it out at the moment.
Thanks.

Since T-Mobile is a GSM carrier, WCDMA (3G GSM) does support simultaneous voice and data.

I popped the T-Moble sim in over the weekend and was able to do simultaneous voice and data, which is great.
I just wish there was a way on this phone to do it on a CDMA carrier.

I'm not familiar with the issues, but so far so good with T Mobile's service. The phone came with lollipop installed and I upgraded it to Marshmallow over wifi before I popped in the T-Mobile sim card. The GF uses it with their service and has had no problems so far. All the different data modes work from LTE down to 2G, messaging and calls work as well.

Does US991 permit T-Mobile's Wifi Calling, which I believe is linked to its ability to provide free Gogo In flight free texting on major airlines?

No it does not have the wifi calling ability. That only comes on T-Mobile branded phones.

I'm also wondering how to activate Advanced Calling on the US991 model for Verizon. I have it activated on my account I just cant seem to be able to make it work on the phone. Any help would be appreciated.

From what I can see in the hidden settings menu, it is not possible. This version of the phone does not support VoLTE. When you click on VoLTE in the hidden menu it tells you something along the line of it not being supported.
