Truemove H and 4g

[MaiChai]

Seems a bit mad to me, but to get 4g upgraded from 3g you need to go into a True shop and get your sim swapped over. Wife and I got new phones (same model Samsung J7 Prime) and got our sim cards swapped to nano sims; went into a True shop to get this done. Strange thing is I still only get 3g while the wife gets 4g. Suppose I will need to go back to the True shop and try again? Back in the UK, never had all this hassle, my 3g sims just worked when 4g came along. Anyone any experience or knowledge on why this is so messy in Thailand?

I've changed my True SIMs several times. Once to do with them moving from True to TrueH, and twice to do with me changing my device to one that uses a smaller format SIM.

 

As it's free and the staff at the True shop do it all for me, I dont worry about it.

Could be many, many, many different things - service provider's system provisioning, SIM issue, phone capabilities/set-up, service plan.... - and without even the most basic of information (phone make/model/sw) it's a crapshoot.

 

 

 

Just don't leave the shop until it works as expected.

I'm not with true but had to do the same with Dtac. It didn't take long, no more than 10 minutes. It's worth doing, 4G in Thailand is pretty fast and reliable, with good network coverage. Much better than in the UK in my experience

 

Edit to add - they may ask you for a copy of your passport when switching over, that's if they dont have it on file already. Take it along with you just in case

The first thing you have to do is to determine if it is the SIM or the phone settings. Put your wife's SIM in your phone and see if 4G works. If it does, the SIM is the problem. If you still have no 4G, it is your phone. It may be as simple as your network settings.

I have True and if you had SIM upgraded for 4G and it still doesn't work, just reset your network settings which should get you up and rolling with 4G. You will probably have to input any wifi logins. Good luck.

1. Select Apps.
2. Select Settings.
3. Scroll to and select Mobile networks.
4. Select Network mode.
5. Select WCDMA/GSM (auto connect) to enable 3G and LTE/WCDMA/GSM (auto connect) to enable 4G.

when i switched my old 3G sim, AIS also instructed me to go to any AIS/Telewiz shop to get a new sim. i was told that the sim i had that time was not compatible with 4G. the sim card size didn't bother me because i can just cut a standard sim to fit micro or nano slots.

 

+1 Gary A's suggestions. also, try calling their customer care hotline for assistance if dropping by a true shop can be a hassle. i hope OP can get 4G to work on his phone soon.

A bit of topic but would a 2G sim card be compatible with 3 G (I'm talking Auss here ) as Tech Support said no problem, which now brings me back to Thailand as my wife had to swap her card when Thai shut of 3G

a SIM card only carries subscriber account identification and provider information necessary to connect to a wireless network infrastructure. When an older card is no longer capable of being updated in-shop or over-air with current provider changes it's necessary to swap the SIM with another newer SIM.

 

As to your question, using an older card in a newer phone may allow the phone to connect to an in-place 2G wireless network if the SIM data was still valid, the phone modem capable, and the subscriber account active.

Thanks RichCor

Maybe my sim ok as Optus phone company was willing to give me a free phone since Auss is switching off 2G (even though my plan is sim only)
