I hope someone can help me or at least point me in the right direction.
Im in the Philippines and my g1 is unlocked/rooted with the latest cyanogen rom 4.2.6.
The network im connecting to is smart communications with according to http://en.wikipedia.org/wiki/Mobile_network_code has:
515 03 Smart Gold Smart Communications Inc Operational GSM 900 / 1800; UMTS 850 / 2100
our phones have Modes GSM 850 / GSM 900 / GSM 1800 / GSM 1900
WCDMA 1700 / WCDMA 2100
So i should be getting a 3g signal or something but im not, my phone is not even making an attempt to connect to 3g. I have checked the settings and i cant find where to enable 3g. Use only 2g network is not checked. my apn settings seems to be correct but its not even getting to the point where it tries to connect to 3g. I have no 3g symble or edge symbol. please help..
help someone pls
Hello everyone,
I bought a G1 from Rogers in canada, but now I live in germany.
I don't know how it actually works, but I have been unable to get 3G connections here (only GPRS and normal cell phone), using the O2 company. After doing some research I realized that the radio frequencies are different (according to http://www.gsmarena.com/network-bands.php3?sCountry=GERMANY, then go to canada to check it out).
Are there any possibilities to change the radio frequencies of UMTS? My phone is rooted.
Thanks a lot!
Dial:
*#*#4636#*#*
Then goto phone info
Scrool down list
Change preffered network to WCDMA only for 3G only
Exit
Edit: O2 doesnt use the same 3G freq as Rogers, so you must stay with EDGE.
if memory serves correctly - o2 and tmobile work on the same frequencies in germany
if this is the case there is nothing you can do as the radio frequency is a hardware thing
Thanks for the reply!
I did that, but after a while it changes back to 'WCDMA preferred'.
I went to the O2 store, and the guy tested the chip with a Palm Pre, and it worked fine.. but with my G1 it didn't, only GPRS.
rogers use different frequencies to most other providers worldwide
rogers, atnt and some south african one use one set for 3G but everyone else uses another
you WILL NOT get 3G on the rogers dream on frequencies not used by rogers
also

will this work with any phone? Sorry NTT. i have just bought a htc touch 3g but it won't work in the bush. the phone supports HSDPA/WCDMA:
900/2100 MHz and out here we have 850/2100 mhz wcdma.

All I know is that it allows you to force a specific phone freq, im not sure if all HTC phones have test mode which that number brings up. It doesnt allow you to change the freq only force one type. So a quad-band phone can be forced to use 2G only instead of 3G.It doesnt give access to unsupported bands cause thats a hardware thing.
I am discussing this very subject here: http://forum.xda-developers.com/showthread.php?p=15461093&posted=1#post15461093 would appreciate any comments or suggestions.
Is there any way to get my Captivate to stick to 850 band only, and not switch to 1900. I live in an area where I have 3G coverage on both bands.
Edit: I can get to this using SGS tools, but that would be only till a restart. Any way to get this to stick permanently until disabled.
Go to the phone dialer and put in *#2263# from there you can select what band you want. To check if it took, type *#0011#
Yes.. what he posted above should work even after reboot
The moment I set to 850 its switching from 3g to edge. Strange. Cos when on 3g mode its always been on 850, atleast 80% of times

Thats one thing the bugged me is that this phone ... AT&T version anyways.... loves to camp on 1900mhz more and would be fine if it would switch to 850 when needed..... alot of time I would be at -111db and still on 1900 when 850 in the same are would be at -103db.
I enable 850 that way but once you reboot... you need to do it again.....

Technically, the lower band should have lower signal strength reducing radiation. Plus should be using less battery power. That is why I am seeing how to get to 850.
Anyways, I think I'll leave it how it is.
Got an used Captivate on eBay, came with kernel 2.6.35.13 Glitch v13.1, MIUI 2.2.17, Android 2.3.7 and modem UGJK4
Well, Captivate radio specs for 3G: HSDPA 850 / 1900 / 2100
My operator (TIM) uses 2100 in my city, excellent until now!
But, I'm stuck in EDGE, can't get it to connect any faster. We have other phones here got from England, Ireland and USA, all of them support 2100 and 3G works perfectly, but not this Captivate.
Already tried the following modems: UGKG3, XXJTV, XXJVU and currently on UGJL2.
Just after installing the UGJL2, it connected at HSDPA, but after 5 seconds changed to Edge and no (H) anymore
A weird thing, I tried another operator chip (VIVO), that also operates at 2100 in my area and HSDPA is enabled normally!
Got back my chip and back to EDGE, this same chip get 3G+ (HSDPA) on a Samsung Jet, Samsung Galaxy Mini and a Samsung i550.
Everything else works perfectly, calls, GPS, wifi...
Any tips?
Thanks!

From what I know, the Captivate only gets 3G on AT&T even when unlocked. I might be wrong, but I remember reading that somewhere.
Must be a myth, I use my captivate on 850mhz in Australia 3g and hspa work perfect.
Did you try to force 2100 with service mode?
Phoned in.....
But with the other operator chip 3G works normally, at the same place where my chip also get 3G on other phone. Both are 3G+ (Hsdpa) able, but not when together. That is what makes no sense.
I would have forced in servide mode, but all the codes for service mode does not seem to work, and I've seen around the forums that MIUI don't have it...
Is there any code besides *#0011# and *#*#197328640#*#* ?
Both not work here
Thanks for the help!
MIUI and AOSP do not allow for the forcing of certain bands. You can specify what region you are in, but that's about all. To do that, use dialer code
*#*#4636#*#*
Phone setting
Menu/select service bands
That's about as good as it gets.
Hope it helps.

Your carrier uses the same 3g bands that att does. Those are the only ones that use the same 3g bands

Yes, I've tried Automatic and Euro (same bands used here), still Edge.
The strange thing is it get 3G from the other operator, that uses the same 2100 frequency... (at leaset they say it's both 2100)
Any way to see the frequency currently in use?

My carrier uses 850 and 2100.
My wife has a captivate also, her carrier uses 900 and 2100. Of course only the 2100 works but it is solid.
Phoned in.....
Ok, I discovered that it's an area problem probably, I tried at the office and got the H on the indicator! HSPDA is working, sometimes 'came down' to 3G (concrete building, not so good signal).
That's still strange because my friend get Hspa here, with a Galaxy S (I9000b), same operator, will call them soon to ask about this.
Anyway, it works! with ridiculous speed (180kbps), but it's better then Edge at 15kbps...
Thanks everybody for the help!
I am in a country where all Network Operator uses Band3 (1800Mhz) for LTE. And i have search everywhere and it is clearly mentioned that mi5 pro do support lte Band3 and yet i can seem to be able to connect at all!
I am using China Stable version 7.5.6 and yet just cant connect at all to the LTE Network even when i manually tries to search and register to 4G Network, it just goes to No service then Emergency Calls only. :crying:
Hope anyone can help me out with this as i find it very sad that i cant use 4G in my country.
I have already tried several times to change stuff on the *#*#4636#*#* menu but still it just does the same thing. i have sims of all 3 operators and yet none of them connects to the 4G networks.
Maybe add the APN and turn on data for the sim you're using?

It should certainly work as I'm with Three who operate on 800 and 1800 and 800 isn't supported but I still receive 4G signal. As mentioned try manually adding the APN for your network?

I don't have the 'prefer LTE' option under mobile network but still can connect to LTE network in my country (1800Mhz), this happens for both china stable 7.5.6.0 and global stable 7.5.2.0 ROM
Can you update to lastest Xiaomi.eu version (Miui 8) and check the 4G on that 1800band?
