Is there a way to determine what GSM frequency my phone is currently using? I'd like to make sure that 850 is enabled and that I can use it. (best signal here)
Does anyone know of an app which will allow me to check the reception for a specific frequency band (850/900/1900/2100)? The Test menu allows me to see which band is currently used, but I can't see (AFAIK) if another band also has reception...
Is there a way to check that the LTE radio on the ATT SGS3 will work with the 2100mhz band LTE in Thailand? I tried an updated SIM at the True Mobile shop this morning and my phone would not register on the LTE network. When selecting "Bearer" in APN settings, picking LTE would disconnect my mobile date - setting it back to 'Unspecified' allowed me back onto HSPA+ but not LTE.
- Is it possible for a carrier to restrict the types of phones that can access their LTE network, or is it as simple as having the correct radio?
- Are there different channels on the 2100mhz LTE spectrum, and is it possible ATT uses a different channel than True is using?
- How can I diagnose my radio connection to determine what could be preventing my access to LTE on the True network?
- What is the difference between LTE 700mhz Class 17 / 2100 and 2100mhz LTE?

True LTE - 2100 mhz band 1
i747 LTE - 700 mhz band 17, 1700/2100 (AWS) MHz
- Is there a way to see if I am connected to their 850mhz 3G or 2100mhz 3G?
Please let me know what further information I can provide to facilitate a solution. Cheers and thank you in advance.
[EDIT] Upon closer inspection, these are loafers... er, rather I educated myself about LTE bands and AWS... a tad confusing, but going off of the Samsung website spects, the SGH-i747 is dual band LTE 4/17... which is incompatible with True's LTE band 1.
This may be the push that puts a SIV in my hands...
I'm in the UK this band is supposed to work on this phone I've tried forcing it nothing seems to work.
My sim is 4gg (giffgaff) APN is set and I'm in an excellent signal area for 4g.
???
Work in my other phone's.
you're right, band 20 is supposed to work but unfortunately I'm on 3UK so can't check for you(though I think 3 does use some 800mhz spectrum depending on area) - so 3G works for you only? Have you tried to force 4g using the mtk engineering app(android settings>phone info>set LTE only from drop down menu)
Hi, I have the S20+ purchase from carrier here in Canada. When I play online game or video conference from time there is connection dropping for 1 or 2 second sometime up 5 second. Its very frustrating during gaming. My 3yrs old LG never had this problem, my signal is always 1 bar away from full.
Setting on LTE/WCDMA/GSM and 5G is off as my carrier doesn't support 5G yet.
I read on the samsung forum many people had worst problem with early firmware. Does anyone know any idea can help improve this problem. I did a Network settings reset didn't help.
Hello,
You can try forcing only low bands or only high bands. You must remember to change back this setting if you want faster speeds or more coverage. The low bands will typically help with stability and the high bands will typically help with speed.

You should see band selection. Choose clear all. Choose WCDMA 850, LTE 5, 12, LTE 13 and save.
If you mess it up, press clear all then select all and save. It will set your phone back to the original band selection.
I get almost the same here on Sprint in America. I see connection drops (while still connected) and some data slowdown.
It happened on my s9 plus so I just knew to reboot. I think it's more carrier end then phone, unless it's just Samsung in general

Thank you this been working for the last 10min testing. I had to say on the speed test before I am getting 200-250mbps/sec on download now at 15mbps. It be nice I can get it to around 50mbps .
@creep138 I had Iphone, Asus, Sony and LG never had this problem. Yes, Samsung speed test is a lot faster but I rather have a stable connection than faster.

You're welcome. You can choose to include band 2 or 7, depending on your carrier. But it will kind of negate the reason for choosing lower, more reliable bands in the first place. Good luck!

I google my carrier LTE bands and did some testing.
700 MHz Band 12, 13, 17, 29
850 MHz Band 5
1700/2100 MHz Band 4
1900 MHz Band 2
2600 MHz Band 7
7 is is not stable and 2 is much more stable and good speed over 100mbps.
