My phone will only work with GSM. - G4 Q&A, Help & Troubleshooting

My internet works only with GSM.
When I change to LTE / 4G it will not work.
I flash back to stock.
It has worked LTE 4G earlier.
I have the correct APN set.
Could it be a setting in my phone or hardware?

[Q] [XI] LTE not working on my Ion

Hi,
I have a Xperia Ion, Firmware .68 LT28i, rooted, I can't seem to get LTE working... I have tried using *#*#INFO#*#* and changing it to LTE but my carrier defaults to 3G (H symbol) I am in HK, and i know LTE is available, because i went into the carrier's shop and they tried putting my sim card in a Samsung phone and it showed up as 4G. So, are their any settings i need to change to get LTE? The download speeds are slow so i i don't think i am on LTE.
Thanks
Bolo

Feck. It seems LTE Band 4 and 17 are not actually supported by any of the networks in HK, What a waste of time this is then. LTE seems to be a bit of a mess with so many different versions of the same phone required to support LTE!

Lte not working. Help please.

I have an htc m8 unlocked international model and which does support 1800mhz frequency for lte, the same my network provides for lte. But i am unable to run lte. tried my sim card on an iphone 6 and lte works just fine. Please help me.

The same problem is getting me as well. According to the Network provider(WaridTel Pakistan) this model of HTC One M8 is not supported in Pakistan or Carrier Lock something even the LTE option is appearing in network modes. Meanwhile 3G and edge is working perfectly.
HTC one Mdoel Name: OP6B160
Network: waridTel (LTE 1800 MH)

Thanks a lot. It works supports GSM fine.
What about 3g? Does it support that as well? It says CDMA while other mobile specs mentions UMTS.
If you own this set. Can you confirm if the GPS works without internet?

Hi AhmedRana
I have ls950 and am using in India with GSM operator Vodafone. Both 2G and 3G data work fine.
I could not test 4G As India is using LTE band 40 which is not support by ls980.
I think the phone GPS needs data connection to work.
Hope it helps

You know, if you just do a simple Google search, you'd find quicker answers. Works all the time.

LTE CAT 3, HSPA+ 21 Mbps*
EDGE, GPRS Class 10, UMTS, HSPA+, WCDMA, LTE Bands 25/26/41*

i m using this phone in india with cloudy g2 2.2 works good on all networks 2g 3g .. gps works without data connection..
buy it .
I am using this phone on Cricket in U.S. which is ATT (GSM) and I'm getting HSPA+ speeds.
Sent from my LG-LS980 using XDA Free mobile app
The LS980 (Sprint G2) works fine on 2G, 3G/UMTS, and 3.5G aka HSPA and HSPA+ networks here in the U.S. for AT&T and T-Mobile - it will not work on any LTE networks in the U.S. except Sprint's network because it is limited to using their particular LTE bands (bands 25, 26, and 41) which do not have any crossover for AT&T (bands 2, 4, and 17) or T-Mobile (bands 2, 4, and 12).
With the last G2 I had (might be getting another one later today, another LS980) I was easily pulling down close to 39Mbps using T-Mobile's HSPA+ without issues which is just shy of the theoretical maximum of 42Mbps so it worked great for me, YMMV as always.
for 3G, isn't LS980 limited to UMTS band 2100 ?
what about the other bands 850/900/1900 ?
Back of phone's box. See by yourselves.

[Q] LG G4 (F500-L) on T-mobile?

I currently have a Korean variant (F500-L). I have seen a couple of these for sale on swappa and both posts say that this phone will work with T-mobile LTE. However, when I've popped in my SIM, I only get 3G. Does anyone else have any experience with this variant on T-mobile? If you were able to get it to work on LTE, how did you do it?
Enter APN settings for T-Mobile. Google that. Just popping in the sim won't give lte.
i have the same issue.. the APN settings seem to be correct.. but it only shows 3G. Model is F500-L
same here i need help too mine is a f500s lg g4 skt version thanks
Far as I know, phone must support LTE Band 2 and 4 to work on T-Mobile 4G network.
But F500(Korean ver. of G4) doesn't support LTE Band 2 and 4. It supports LTE band 1,3,5 and 7. Therefore a phone will only work under 3G network.

4g

I have a HTC One M8, t-mobile, rooted ,s-on , unlocked sim , new sim for 4g ...but I don't have 4g, only 2g, what should I do ... I live in europe albani
You should find out what frequency bands your carrier uses and match that up with what your phone has.
Chances are you have a phone that does not support your carriers 4g bands and its reverting back to the more basic 2 g stuff.
