No 4g at all !

[MotasemBT]

Hello every one I just got new sealed op3 , the old phone was Htc one m9 plus , I used to get 4g connection everywhere .
Now after using op3 I never get 4g connection I only get H sign means 3g ! .
Here some info
I have the correct info for APN and the network is "zain jordan"
Same sim used to get 4g
My mobile model is A3000 , and software is oxygen 3.2.7 Android 6.0.1
I checked my mobile on gsmarena for the frequency and checked my operator frequency and they match (2100) should work !
I contact OnePlus fb page they didn't give me straight answer.
When I go to cellular network setting and search manually I only get 2g and 3g networks for the 3 operators in our country.
What's the problem and what can I do ?
The cellular customer service asked me a simple question , if you put the sim in another phone will you get 4g ?
I said yes
They said : your phone problem ...
Help please XDA

I wish I had an answer to your exact issue but I do not....

However I had a similar issue on US ATT. Put the sim in never got 4G/LTE only 3G and I went to ATT thinking a new sim would fix issue. It did not.

So I said what the hell, left the sim in and did a factory reset of the phone. When it came back up I have 4G to my surprise. Prior to that I changed APN, had ATT give me a custom APN and reset APN on their end....no luck. Factory reset did it and I did not want to do it since it would wipe my data....but finally doing it worked.

My $0.02

Are you with AT&T? If yes look online and you'll find guides and hope to get 4G.

Have you tried restarting your phone? It's stupid but I couldn't get 4G before I did.

As soon as I got my new OnePlus 3, I was not getting 4G in my region either. I had just the same problem as you.
First I got in contact with my carrier, but nothing they could do, as they said the problem was on my end.
After messing around a lot, with all possible network and APN configurations and not getting any results, I got in contact with OnePlus customer support, to no avail either, as they could not find any explanation if not for problems with my carrier.
And then, one of these days, no update or anything relevant at all, it just started showing the LTE icon. The phone did not receive any updates in the meantime, I did not change any connections settings, literally nothing on my end changed at all.
The problem just fixed itself it would appear.

I had the same Damn issue. Make sure the writing on your box's label is in English. I finally figured out I had the Asian version of the phone. Was nit compatible with usa 4g lte bands

Try entering:

*#*#4636#*#*

in the dialer. Go to Phone Information and make sure the preferred network type is set correctly.

When I received my OP3, it was originally set without LTE.

Guys the problem for me is my device model is a3000 and not supported by my carrier frequencies .
I didn't know about this and I must get a3003 .
So it's dead end . That's what OnePlus told me.

Any turnaround for this problem ? Or should I give up ?

Not sure why Oneplus sended you a A3000 then. They should replace it at their cost. Not sure what your local law is.

Where did you buy it from?

If you are not able to get it replaced by the seller, I am afraid that it will be curtains for 4G. No point in blaming OnePlus if you have not directly bought it from them.

Go to "SIM Cards" settings and Choose "Preferred SIM for Cellular Data" as your 4G SIM.
If your 4G is VOLTE, it should be selected as preferred Data Network in order to get network.
