4G LTE switch on TMO V10 - LG V10 Q&A, Help & Troubleshooting

I have a tmo V10 from one month.
Factory and Legit unlocked by tmo to works for all networks worlwide.
I use it in Italy.
I love him and this is perfect in all things but i have a problem :
4G LTE it works like a charm but when i power on device or switch from wifi to LTE or switch from airplane mode to LTE : data connection is not present and 3G too, no data at all, 4G LTE icon yes.
I can't open web pages and use my data plan.
To make works I have to switch mobile data to : GSM/WCDMA wait that 3G signal is on and then turn back to WCDMA/ LTE Auto - and so, after this i have full 4G/LTE signal working .
I suppose could be caused from a tmo app in background that block first LTE or generic Data access

[Q] H+ icon, what does it mean ?

Hi
I have the Galaxy S2, when I turn on the use packet data and data roaming in the mobile network settings, an icon H+ starts flashing on the top of the display with two little arrows.
1. What does it mean? Is the phone downloading data from the cellular network?
2. What is: packet data and data roaming? What's the difference between the two?
Many Thanks.
Hi,
The icon itself means that you are connected to the data network of your cellular provider.
The icon can look like one of the following:
G - 2nd (or 2.5) generation connection
3G - 3rd generation coonection
H - 3.5 generation connection
H+ - 4th generation connection. This does not mean your provider actually support 4th generation data rates.
When the little arrows are gray - No data is being sent/received. When they are colored it means your phone is sending/receiving data.
Roaming means that you are connected to a "foreign" cellular provider (not the one you are paying to).
Data roaming means that you allow your phone to use data connection when you are roaming.
Using data connection while roaming is extremely expensive and it is highly recommended not to do so.
Hope I got it all covered for you

Thank you for clearing this for me.

well I did my digging and got some more accurate figures in addition to the above
G is GPRS 86kbps
E is EDGE 236kbps
3G is UMTS 386kbps
H is HSDPA 3.2Mbps
H+ is HSPA 7.2Mbps
H+ is too for HSPA+ for 14.4Mbps or 21.1Mbps
(noteH and H+ are the so called 3.5G
and the new comer:
4G ( LTE technology) is 100-300 Mbps ( the iphone5 is said to be on 100Mbps)
some phones don't show H or H+ , they just show 3G for UMTS, HSDPA, HSPA, HSPA+
only G or E means it's on 2G, - that is you are not in 3G coverage
PS on my Vodafone, using speedtest.net app i get on H+ 7.12 Mbps... ( aka 0.89 MB/s)
Period

Is there a different icon for DC-HSDPA, or is it 'lumped' into H+?
The standard should theoretically allow up to 84Mbps with MIMO, but my phone only supports up to 42Mbps.
KPN in NL has it rolled out, but I've never been able to confirm if I'm on DC-HSDPA. Using Network Signal Info android app, the fastest I've connected is HSPA+ at 21.6Mbps.

Got any airtel 3g hack ????

does anybody got a new hack for airtel network ???
what hack???
I'm guessing he wants to enable a normal 2G internet plan on his network for cheap, but use it in 3G by switching to 3G mode. As far as I know, with Airtel the only time I've seen this work is with my friend's AT&T Galaxy S2 unlocked from the US. It's a 4G phone and it doesn't have the usual 'GSM only', 'WCDMA only', 'GSM/WCDMA auto' modes under network settings. So when he recharged for a 2G pack, the phone connected to Airtel's 3G network and displayed a 'H+' symbol in his status bar. He gets 3G speeds quite a few times but sometimes it becomes as slow as 2G. I haven't seen this work on a normal phone bought in India.
I used to get 3g speeds on 2g internet pack from airtel.I always keep the network mode to wcdma.
But sometimes i also get very low 2g speeds.
All this on my old samsung galaxy s

Moto E XT1527 - unable to detect 3G network

Hi,
I recently purchased a XT1527 - AT&T go phone and it was working well in USA as I got 4G signals all over.
I am now back to India using Idea network, the phone gives me only 2g network
I even tried *#*#4636#*#* and set the preferred network to
a) WCDMA only - couldn't find any network
b) LTE only - gives me only 2G
c)LTE/WCDMA - got only 2g
I also don't see the preferred network options under
Settings->wirless and networks->more option
how to resolve this issue?
Att model may not have the radio bands you need to get anything higher than 2g. Sounds like your issue with me.

The North American models only have the 3G/4G bands for North American networks. You'll only get 2G internationally.

G5 cannot connect to 4G LTE?

I bought a Sprint G5 (LS992) and am using it in Canada, however I have never been able to connect to 4G LTE even though I am sure it works on my carrier's LTE network (Public Mobile, which uses Telus's network). I could still call, text and use data on 3G HSPA+ but not LTE.
I checked the Network type and strength under Mobile networks and only see 3G -65dBm.
In 4G settings under Mobile networks there are two options, one is the Network operator which I could not press into it and the other one being IP address which shows me "0.0.0.0"
Tried to enable LTE by switching the network mode to LTE/CDMA only but not even able to connect to the network (no calls no text nothing)
I am pretty sure G5 is capable of using LTE but just don't know why I am not the one using it.
Thanks for any help or suggestions!

X829 Metro PCS 3G not working

I'm in USA X829 currently on METRO PCS GSM carrier. I'm getting LTE fine but its not switching to 3G. I'm currently running linage ROM. This phone does support 3g band for my carrier. My question, is there a secret menu or something to setup a priority for LTE 3g? I know on some TouchWiz ROMs this is possible. I've also tried flashing Chinese, USA and the developer modem. Would only get LTE or H H+. Would not show 3G and wouldn't get any data till I'm in a LTE capable area.
Did a little more research H+ and H are faster than 3g. But I wasn't getting any data when they turned on
