3G (UMTS) bands. - Optimus One, P500, V General

Hi,
I have an Optimus One from Telus (canada) so I know it has at least the 850/1900 bands , but I might take it with me back home where I'd need the 2100 band. Is the information on wikipedia that says that it has tri-band UMTS true? and how can I know if it has the band I'm looking for (2100Mhz)??
Thanks in advance.

In the service menu (type 3845#*500# into the dialer, replacing 500 with your exact model) it has a menu for network mode which has a WCDMA 2100 in it.
The question is whether that is functional or just part of the stock LG testing set, I don't know, originally i tried to change the band on mine but ran into continual dead ends and had to concede to go with an alternate sim/network.
Guess you'd have to try it to find out.

The service menu doesn't come up. I think it's because I have the cyanogenmod ROM.
I found the service manual and it had this section:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I'm not sure if it confirms/denies that this phone is indeed tri-band as it had all 4 UMTS bands in there!!!

mhm, hard to tell, at the end of the day i'm not sure you can find a definitive answer without being able to test it. the service menu is just an apk as far as i'm aware, you can probably flash it.

Anyone get LTE working AT&T/tmobile

Just got my Tmobile variant unlocked and using on AT&T. Only getting 4G. I've seen users having the same issue. Has anyone got LTE working? I've tried numerous APN's from AT&T as well as other suggestions and still nothing. Thanks in advance for any help.

I have a T-Mobile phone as well, and I had a more complicated problem getting mine to work. First thing's first - make sure you have your phone properly activated at an AT&T retail store, which is to say you can't have hotswapped the SIM; it needs to be tied to your IMEI. If it still doesn't work, make sure you're using the nxtgenphone APN. If you still have no luck, maybe you have the same problem as me. On AT&T's end, for some bizarre reason, my IMEI got registered as one that could not support LTE, so my line didn't get provisioned for it. I kept calling back, but no one could figure out how to change my provisioning. Finally I got a rep who tried something out of the box. He generated a "dummy" IMEI number for me, one that would be seen on the system as one that supports LTE, and registered that to my line. Lo and behold, that did the trick. I called Technical Support for this (you can ask to be transfered to that department if you call AT&T), so you might have to go through that - the good news is, it was rather quick, and I didn't have to get a new SIM card for it.

Well, I tried to find the way to activate 4G band on this model too but nothing found. There is no Power Amplifier and antenna for LTE band in this phone, so even if the band been activated in CPU it will not work at all.

You can't enable band agregation, it's an hardware feature. Your phone can connect either to B3 or B7 depending on Your carrier and Your location but not the two at the same time.

not understand. in india Jio network support B3+B5+B40
The op want to activate "4G+", which is one name for band aggregation. The redmi note 3, even the special edition, does not support that.
If the op just want to activate the B3 and B7 bands because his carrier support this two bands but somehow he never connects, it's another problem, and idk how to help with that.
The default configuration of the RN3 should support those bands. I'm located in france and it doesn't matter which rom I use it connect to B3, B7 and other depending on where I am.

Modem from 1 to 2 was stitched, but it works not correctly, I had to return my native
The image of the modem is saved from two phones, it is possible to port B1 in a modem without B1?
Xiaomi Redmi 8 A similar processor, the possibility of porting the modem?
Good Morning Yan,
I have no Rakuten Mini phone. I hope to be of help, though.
According to Rakuten, there are three versions of the Rakuten Mini phone :
https://network-mobile-rakuten-co-j...ec.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=fr
Click on "Supported frequencies" to have all details.
The third version, with serial numbers (IMEI) 351676110682491 to 351676113417929 does not have LTE band B1, but it has LTE band B4.
Rakuten also says here, that "When adding frequency bands to the design [...] the number of frequency bands that can be supported by mobile terminals is limited. Some frequencies etc. have been deleted."
If you just add B1, you may have too many frequency bands.
It is my understanding, that you used an older version of the modem file. This should remove B4 and add B1. But I may be wrong.
Please check that you deleted band B4 to "make space" for band B1.
Please keep us aware of your progress.
Have a nice day !
Cobus.

cacombos.com

I was seeing that in a xiaomi forum they use QXDM to modify the CA2 band, as most operators use only 2 bands for LTE-A/LTE+, could someone verify if this is possible?
[GUIDE] Enable 4g+/LTE-A Carrier Aggregation without Root on Stock Rom
As we all know, MiA1 has a Snapdragon 625 processor that comes with the X9 LTE modem which supports Carrier Aggregation (2CA) but the OEM has not enabled it. With the help of this guide you can enable carrier aggregation in your mia1 even without...

It is similar to the cross flash procedure that is done to change the sprint firmware. I hope your support colleagues.
