I need to change the settings in a Samsung SGH-i637

I have just replaced my Samsung SGH-i616 (Blackjack 2) which is on the Fido network, with an unlocked Samsung SGH-i637 (Jack) which was an AT+T phone. I put my Fido sim card into the new "Jack" and the phone works as a phone, but it will not send or receive e-mail, it will not log on to the internet, the call display does not work, etc. It will connect only through Wifi if I am near an access point. It appears as though I can't access my data plan with Fido. How can I remove or change any of the AT+T settings?

Can't receive calls while using data in s4 mini duos? Solved

I had this problem: In my galaxy s4 mini duos (gt 9192) I use both SIM cards for voice and the SIM 2 for data connection. So SIM 1 is in GSM only mode and SIM 2 is in GSM/WCDMA auto select mode. I leave the mobile data always on and I got lot of dropped calls to the SIM 1. Every time I pick up the phone there were lot of messages which were Missed Call Alerts to the SIM 1. There was no problem in receiving calls to SIM 2.
With some testing I noted that the phone does not receive calls through SIM1 whenever the data connection indicates H+ sign ( Data connection is though the SIM2). Yet I could receive calls when that data indicator indicated as 3g. Finally found a solution to this.
Solution: Go to Settings -> My Device -> SIM card manager and put the tick on Receive Incoming Calls, which is the first entry under General tab.
It gives a warning message saying the data speeds will be reduced by enabling this option. Still when I enabled that option, I did not see a significant reduction in speeds. I get all the calls from SIM1, yet the data connection drops whilst the phone is on a call in SIM1.
Think this works vice versa, that is Data is on SIM slot 1 and voice only SIM is on SIM slot 2.
May be this is a well known thing. I posted as this might help someone.

Can not make or receive calls from Mexico

Can not make or receive calls from Mexico and unfortunately my the official solution is to use ... the Galaxy S7 not even the S8 the S7
Unless I can find a way to make my Phone work I will have to try the Galaxy S7
What happens when somebody tries to call me most of the time they get voice mail.
When I try and call out most to the time after a few minutes the phone says Call Failed.
Now I have the RSSI at max on the phone do not think the connection is weak.
The phone always receives data emails and messages.
In Mexico the carrier is Telcel
I talked to my company and Rogers "Canadian" they both say I have the right plan and like I said calls to happen say one out of ten tries.
I tried all sorts of things to get voice calls to work every time
Went into service mode manually selected bands "some where it said try Japan my phone does not have the choice"
Tried to disable 4G
Tried to find another network but Telcel is the only choice I have.
Please somebody give me something to try ?
I do not want to use the Galaxy S7
Lose unlimited photo storage
One of the best cameras I tried
Older and slower device
Lose Android updates
Lose Google Assist
Go from 128Gig to 32Gig is painful (mind you I can use a microSD card)
Gain Samsung bloat
But the solution given if I can not find a solution is to use this device.
I really half suspect if I do go with the Galaxy S7 I will not get any improvements.
What can I try to get voice calls work in Mexico ?

Probably a dumb question but did you enable roaming?
From the home screen, swipe down the Status bar.
Tap the Settings icon.
Tap More.
Tap Cellular networks.
Tap System select.
To disable roaming, tap Home only.
To enable roaming, tap Automatic.
To permit data access while roaming, tap to enable Data roaming.
Note: When prompted Allow data roaming, tap OK.
The roaming settings are now changed.

Yes it is roaming Telcel "5 bars" and R "for roaming"
As I said data is no issue, messenger, email etc....

Did Trump already build the wall?

Have you tried to reset the network settings?

if your data is working but calls are not verify your apn is set up properly.
try using hangouts dialer and see if that call goes through, if it does then it's going to be the APN. You can copy it line for line from your s7

l want to thank everybody that contributed.
I am back home in Canada so I can no longer test.
When I go back again I think just for the kicks I will bring the Galaxy S7 just doubtful if will work but who knows.
Still will try and get the Pixel XL to work.
I can not see how it would matter, Pixel XL, Galaxy S7 or whatever if the phone supports the Network it should work.
Now I seen people using the Galaxy S7 receiving and making calls ?
Will have to try it.
On the other hand I know people making the same complaint about Telcel
I checked the difference in hardware Pixel XL / Galaxy S7 they do have a few differences in the bands they support ?
Reset network connections I did think of this but but the warning seeming pretty scary.
If the Galaxy 7 works for phone calls in Mexico for my next trip I will reset network connections. Worth a try, I read googling a few people had similar issues and this worked.
APN the phone works Data and Voice in Canada, in USA but Data only in Mexico "voice one out of 10 calls". Just not sure
Either way I like new phones and the Pixel XL is better.... Pixel XL 2 may want that too

Galaxy Watch Active 2 LTE - Unable to make/receive calls

Hi folks,
I recently bought an Active Watch 2 and already have a Vodafone UK mobile account to which I added the One Number service.
I've discovered that on my watch while on 4G, I cannot make or receive phone calls.
There is definitely a data connection there, as I can send a text message or use the Internet browser app to view a website.
What happens is I dial a number, I get 2 beeps and then a Call Ended message. I've spent over 10 hours on the phone/chat to Vodafone trying to get this resolved to no avail. I've done a number of resets, SIM swaps etc.
This morning I noticed on the watch under Settings in the Phone app, that there is an option for "Preferred Number for Calls" which is greyed out and set to 'Watch'. I'm sure at one point when I first got the watch I was able to select Phone or Watch. Could this have something to do with it? Is the VF network blocking the call because the watch is trying to phone from the One Number secondary number instead of my contract phone number ?
Any help appreciated!

Hey there.
I have the exact same problem myself, my carrier is o2 and have an Active2 LTE.
Set everything up through the esim QR Code. I am the £5 data per month, and yet am unable to make or receive phone calls through LTE / Wi-Fi. No issues though with data and messaging.
It occasionally worked when I first set it up a couple of months ago, but since the latest Tizen update to 5.0 something, there is no option under 'remote connection' in the Galaxy Wearable app to make/receive calls. When testing my original Galaxy Watch out, the call option is there and it is on Tizen 4.0 and I am able to make WiFi calls.
At first I thought the issue was with o2 but am now thinking it is related to Samsung services. Via Bluetooth the Active2 works fine with call functionality but through WiFi/lte, nothing. The odd issue as well, is that, when testing through LTE on the watch it remotely connects very briefly to the phone when attempting the call but then the phone automatically disconnects from remote dialling.
I would say that it is definitely software related, I also have tried all troubleshooting issues and more with no luck.

Hey there. Have you managed to get a fix for this?
I have been in contact with both o2 and Samaunf on this very issue and Samsung are saying to send it in for repairs. I am very dubious though that it is a hardware issue, rather software related.

Hi I have now got both a galaxy watch and a galaxy watch3 here in the UK to now work stand alone on a pay as you go ESIM and wondered if some of my findings may help.....
First the Galaxy Watch i bought second hand on an auction site
it had been on EE in the UK and when i first loaded an esim on it I could not make calls or connect to the network...
I looked under settings connections mobile networks only to find that there was no option to select 3g / 3g4g mode ....
Hence the unit was setup only to connect via 4g data ....by default ....and so would only send Voice calls over LTE ...and hence when i changed the ESIM from EE yo Vodafone I could not make calls or SMS ...and only had emergency calls over vodafone if i was in a 4g service area with no ability to search for or connect to 3g
So I downloaded OXX versions of the firmware instead of OXA for the UK ...and i got the earliest version i could find.
Then loaded it onto the watch ... then I checked the CSC and EE where using a non BTU CSC code so first...
I changed the CSC to BTU so I could support non EE ESIMs
Next I Uploaded an ESIM from Vodafone via Galaxy Wear on a samsung phone over a bluetooth link after first activating
the esim test feature of wear app to enable QT code scanning to load the ESIM.
The OXX firmware activated the 3g 3g-4g section option under settings connections mobile networks so i could enable 4g/3g auto selection .....then the watch could find and connect to 3g or 4g networks and make voice calls and send / recieve sms.
then I put the watch into firmware download mode to install OXA firmware ...and it was an the oldest version i could find
the watch rebooted and so i now had OXA firmware with the 3g-3g/4g toggle still present under settings.
checked it was on 3g-4g auto selection.
then I enabled Dexv mode and made sure the CSC was still on BTU for generic UK ....it wasnt it had changed so I reset it to BTU
then I upgraded the firmware to the latest version via wear app ...
So end up with a generic BTU UK CSC with the latest Firmware BUT with the 3g/4g selection option under mobile networks.
with another service providers ESIM installed 3g/4g to auto select and it all works fine.
hence myadvice is if you dont have 3g/4g then the watch may be locked to 4g ONLY and VOLTE as its only mode with the CDC set to something generic EE for example...
Hope this is of assistance as many conplain that the watch wont work stand alone for voice calls or sms properly
my days of time and many esim tests until i got 3g support and 3g-4g auto load lead mr to think that the watch is often
locked to 4g data and VOLTE only ....
I now have done this on watch and watch 3 models with full sucess stand alone pay as you go esims ....with the watch fully stand alone...working like a normal cell phone ....with esim service with a different provider to the sim in my samsung phone
comment please .... hope that helps

Hi. My problem is different from this. I can make and receive calls from My Active2 LTE and I can also send text messages. However, I cannot receive text messages. Basically I bought this watch to rely on this for calls and messages and this got totally disappointed me.
Any advise on how we can receive text messages?

I have had this problem too. The issue is in phone settings. Go to ADVANCED FEATURES and turn on ALLOW CALLS ON OTHER DEVICES also turn on mobile data in this setting.

Can't use former Sprint/Ting Galaxy S9 on Ting

I can't use a former Sprint/Ting Galaxy S9 on the Ting network.
Primary symptom: CAN NOT make outbound phone calls.
It has been sitting in a drawer for a couple of years, probably from 2019 to 2022.
I put in a new Ting X3 Sim and activated it.
And it won't make outbound phone calls.
Is it just a parts phone at this point?
Or, is there any hope of making outbound phone calls with it?
Model: Samsung Galaxy S9 SM-G960U 64GB
Geographic location: USA 425 area code.
Ting tells me that:
-Ting no longer uses Sprint network.
-Sprint merged with T-Mobile.
-IMEI stuck with Sprint towers that have been decommissioned.
Nothing to be done - it is now a brick as far as outgoing cell phone calls concerned.
Symptoms:
CAN NOT make outbound phone calls.
- Dial out to another phone, get "attempting"
- returns to dial screen in a few seconds.
CAN: receive inbound phone calls
CAN: send outbound SMS
CAN: receive inbound SMS
Properly registered and activated on the Ting network, according to Ting.
