no 3g signal

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..

[Q] change modem or unlock needed for traveling with a Tmo tab w overcome?

Hello experts,
Would you please tell me if I need a new modem (currently on T849UVJJB, assuming that's stock modem), or do I just need to carrier unlock my tmobile branded galaxy tab in order for me use pre-paid sim from other countries such as Hong Kong or Taiwan.
I have already rooted my galaxy tab and installed Overcome 3.0.0 on it. I am interested in voice + data, but all these different radios and talks of voice calling is disabled on the tmobile server's side (thus only network unlock is required to get voice +data) had me confused.
Greatly appreciate it if someone can clear it up, thanks.

To use any sim besides t-mobile, you need to unlock.
You will need to root your tab, then unlock it.
Since there is no compatable network in China the best you can get is voice and EDGE data.
Use a froyo modem.

Thanks rangercaptain for your reply.
As I mentioned I have overcome rom installed, thus I am already rooted. I also installed from the market galaxy_s_unlock, and it seems to be working (although I won't be able to find out until later when I travel.)
you mentioned it will only do EDGE, which I am dumbfounded:
-most Asia (including China) and Europe support UMTS 2100, known as Band I
-Tmobile galaxy tab spec page listed it supported both UMTS 2100 (Band I) and UMTS 1700 (AWS)
I am traveling soon so I guess I will report back. But if there is any actual report from users that would say one way or the other it would be awesome.
Thanks.

The word "and" is the key. The t-mobile tab has to have 1700 and 2100 bands to have 3g/H. Outside of US t-mobile service area, the 2100 band is available, but no 1700 band.
Go prepared for EDGE and be pleasantly surprised if you get 3g. It has worked out in a few places.

well, I am at Hong Kong right now, and here's what I found:
I am using hutchison 3G, JPE modem.
Yes I get voice. Data: GPRS works, EDGE works (though most of the time is G)
But whenever the icon indicate 3G (even with 4 bar) I get no data, at all.
Here the head scratcher: When 3G swtich over to the letter H, if it is above 3 bar I can get data! But I thought 3G and HSPA is on the same frequnecy and if it works for H it should work for 3G also.

That's because the bands for 2100 match, and the US 1700 band and the overseas 1900 band have a small overlap, so you occasionally hit the sweet spot.

[Q] huawei ideos t-mobile 3g does not work

Hi,
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with 3g. I have looked for APN information and the info downloaded to the phone when I connected to network is identical to what is listed on the net.
tmobile docs url not allowed
i had to add the MMSC setting since it was not there as listed in step 12.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And
wikipedia entry for tmobile not allowed
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.
John

thanks

4G Network NOT accessible on MI5 PRO 128GB

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?

Modem Type For Motorola Phone Power

Hi all,
I am looking to determine what kind of modem the Moto One Power has and what bands it physically can handle.
According to the website - Networks + bands
2G: GSM band 2/3/5/8, 3G: WCDMA band 1/5/8, 4G: LTE band 1/3/5/8/38/40/41
https://www.motorola.in/products/motorola-one-power#specs
I just want to know if the missing LTE bands are just outright missing or just disabled.
Can anyone let me know what the FCC codes are on their phone as well?
