I hope everyone is doing well.

I am not that tech savvy, and have been having trouble getting calls on this A53 5G that I recently purchased off eBay....

Do you know if all A53 5G's have VoLTE support? I need VoLTE enabled for T-Mobile. I can only get calls when I select 3g/2g, which is no good since T-Mobile is shutting that off. When I have selected 5g/4g/3g/2g or 4g/3g/2g I can only make calls and not receive them. A circle with a backslash shows up at the signal bars icon.
Would someone be able to explain how to enable it please?
I do not have the option through Mobile Networks.
I tried to use that samsungband app, but there was no option there either.
I tried to use the *#9090# code too, and then I see what I attached in the images.
Then I don't know what to do further.

I assumed that it does support VoLTE based on Samsung's website, but I have a global version. I think it's from Taiwan.

Thank you for any time and help.

I think I'll be returning the phone, but if somehow I can get it to work...that would be great.

It does have volte yes. About phone > status > sim > mobile voice network type is listed as lte (which equals volte).

I'm aware some are having phone related issues supposedly with the July update. It you don't yet have the July update then it just some people have that issue then for whatever reason lol. Maybe its some sort of settings combination bug but its difficult to say.

I have seen the bars disappear but come back on display wake. But that's the extent of anything there. I receive calls just fine. Haven't updated to July update as of yet though.

Thank you, sansofmyst, for your reply.
I did go through with the July 1 update once I got the phone, but I never tested it out before making that update....
Do you know what this security update is...is the update from Samsung...is there a website that says they know there is a problem and will fix it?

You can look up the update info from browsing to settings > software update > last update. That also includes a link to Samsung's update database where on Google you can use "site:" on it and ie A53 and see when all models are getting updates and their info, etc.

The updates are pulled in relation to the sim card carrier. So if you had a different carrier then it gets pulled in relation to that carrier. Its kind of weird that way with unlocked models and Samsung :)

So, editing as I looked into that further. The carriers do their own locked models. Samsung does the updates on unlocked but in relation to the carriers which is opposite of what one expects. Custom rom works around that where possible.


The reports for July and A53 are scattered around. Other Samsung phones with July update also had similar if not the same issue with fixes expected in Aug update. You could ask Samsung directly. I don't know anything further.

Hello, im using a5360 bri Taiwan edition and it was july security patch that broke phone calls for me on Tmobile. Thankfully August security patch has fixed the issue. Im able to make phone calls and receive them on 4glte with hd voice. Haven't found the option to switch volte on or off. I will check the forums from now on, for future security updates or os upgrades with issues before installing. Have a good day or night. <;

Thank you so much for your help and suggestions about checking feedback for updates! Do you mean the xda forums?

Thanks for confirming what I thought was one of the issues since one of the Samsung representatives mentioned possible issue with update, but for other phones...and that they did not have a date for the fix at the time.

I did not get to try the new update since it was unavailable before my product return date. Sigh, so I returned it before it was too late. I got the USA version with lower ram and memory =/ It still said volte weak cell signal when using that code, but it works on 5g and call this USA version.

I mean Samsung and xda forums or any that discuss the a53 specifically.

I haven't checked that code. I get 5g almost everywhere in h-town. Now im seeing that more consistently after the update. I turn that off on the go though to gain some extra battery life. 4glte works well enough 3 to 5 bars everywhere too.

i thought about getting the unlocked US version cause of the issue too. Recent flaships start with 8gigs ram. thats my logic for getting this model and i haven't been able to fill it completely yet based on my usage no social media or gaming. Everything else i use.

Once software support 4yrs os and 5yrs security is done. I'll consider another upgrade. next patch if i see an issue on any forums with network or phone calls, I'll leave it alone. Im in awe how smooth this phone performs. upgraded from note 3 tmobile edition. Only issue for myself was the broken phone calls.
