Hello all!
I have a Samsung A01 (SM-a015AZ) unlocked from Cricket, being used in Pakistan. Internet over LTE works perfectly, however the phone does not support VolTE and so it is only possible to send sms or call over 2g/3g. There's no problem when making a call as the phone automatically drops from LTE to 3g, however that does not happen when someone else tries to call me. The phone does not drop from LTE, nor do I even get any missed calls/sms notifications, but to the person calling me it seems like my phone is unreachable.
There are 3 options present in the preferred network mode (LTE, 3g, 2g) If I set it to 3g, all calls work fine, but with really really bad internet (EDGE). I have even tried to see if any settings in the advanced network configuration menu (By dialing *#*#4636#*#*) would make a difference, however I've had no luck so far. I would really appreciate it if someone can help me with this.
tl;dr Samsung A01 drops from LTE to 3g to make calls, however does not drop when someone else is calling and so does not receive any calls.

Hi, guys!
I'd need some help with my D620(V10g).
2 days ago I've got a 4G sim, and an unlimited 4G plan, I've selected LTE only in the secret menu (in the "RAT Selection") and 4G worked just fine, but I knew I couldn't receive any call on LTE only, so I switched to GSM/ WCDMA/ LTE. However, I can make calls for about 1 hour everytime I reselect GSM/ WCDMA/ LTE.
Here comes the first problem, sometimes if I make a call, it switches to 3G (I don't know how to activate VOLTE, I don't even know if I can do that) and after I finish the call it doesn't go back to 4G, I have to restart the phone to use 4G again.
Another thing is that sometimes, If I'm connected on 4g for a long time, it simply doesn't let me make a call, it's like the phone would switch itself to LTE only.
The first problem is not that bad, it's not hard to restart the phone to make 4g work again, but the second one is full of pain... I don't want to lose calls.
I would appreciate any kind of help, thanks in advance!
After a call the phone goes back to 4G quite a long time. And everytime someone calls me phone goes directly to 3G and everything works fine. In hidden menu (*#*#4636#*#*) I have put there LTE/GSM/WCDMA and everything works just fine.
Hi!
Just a quick question,
I forced LTE in the service menu but found out that calls and SMS don't get through because they use 3G. The phone switches from 4G to 3g very sensitively, even though a "weak" 4G connection seems to be much faster than a strong 3G.
Is there a way to configure when the phone switches to 3G or is it possible to force 4G but still somehow get calls and messages?
I'm rooted and will try anything
Thanks
Hi, sorry if this is a frequently asked question. I have a new edge and was originally on a 3g sim only plan and all was well. Last week I switched to a 4g sim only plan (BT Mobile). Since then the reception around my house has been really poor, and voice calls almost impossible.
Looking though the settings the only difference I saw was --> Network mod, changed from to WCDMA/GSM (auto connect) to LTE/WCDMA/GSM (auto connect)
If I change this setting back to WCDMA/GSM (auto connect), voice calls / reception in the house if fine (but now 4g is switched off for data).
I don't understand how to trouble shoot this. BT Mobile confirmed good 4g out doors, poor indoors for my address, but I don't understand why voice calls are not so poor. Please could anyone assist in explaining why the phone behaves this way and if it is a hardware fault or perhaps just a software / deisgn issus
Thanks
Hi there,
I have a Canadian Galaxy S6 edge .
I am with Telus and the APN settings are correct. It shows t that I am connected to 4G sometimes , yet there there is no internet and I cannot make calls.. Sometimes I am able to make a call but then signal cuts and and I cant make calls anymore. I am able to receive SMS. and wifi works.
I did factory reset and it didnt change anything.
I just bought this phone from someone, and I didn't really have issues yesterday. The only difference between yesterday and today is that I used Samsung's wireless charger to charge the phone....
Anyone can help? Mobile network si set to GSM/HSPA/LTE
Thanks
Just what the title says. My phone tells callers that I'm not accepting calls and when I attempt to make calls it simply refuses to do so or displayed a "call ended" message without ever dialing the other person. Everything else works fine and I can even make voice calls if I use duo mode instead of mobile. I can also receive calls if the caller uses duo mode.
Have been through everything except an actual reset. Unable to do that since the phone was a hand-me-down and I don't know the PIN. I've about reached the point where I do a hard reset manually but I hate to lose my data. Does anyone have anything I could try to either bypass or recover the PIN or something I could use to get mobile mode to work again?
Your sure you have service? If you do, do you have credit? Both of those would prevent you making calls. You can still use Duo if your on WiFi or you have a data only service. If you are showing that your connected to the network and you are certain you have minutes in your plan or credit available then you will need to call your network provider so they can see if there's any network issues preventing your calls. Check the network operators status page to see if there's issues in your area.

It appears that when using a Galaxy S9+ with ATT service the phone is unable to do VoLTE
The way that I was able to have internet on the phone and voice calling was to go into the APN and set the Network Mode to 3G/2G (auto connect)
That fixed it for me. Still pissed off that I can't use LTE but oh well it will work until I upgrade the phone.

Hello, I have an unlocked s9 that is going through a similar issue in not being able to make or receive calls. Can you let me know how you got the APN settings for 3G/2G? Going to APN settings I only see the nxgenphone setting open and active, which I heard was for LTE.
Also, can you let me know what setting it has to be in the 4636 mobile network settings in order to restore data? Thanks
