[Q] Please help me, no 3g, then no data at all

I bought nexus one from my friend.
I am currently using HD2 with 3g data.
When I plugged in my sim card to the n1, it only worked with edge.
So, I seared internet for some information and I found out something about "*#*#6436#*#*" and change the setting to WCDMA only. Then the phone got no signal at all, so I changed back to WCDMA preferred. Then I did ping test but it did not seem to work very well.
Then I played with some APN setting and I realized that I lost data connection completely (phone still working)
I have tried to reset the phone but no luck.
Can anyone please help me with the problem? I am using T-mobile.
Thank you.

Pull your battery, and look at the back of your phone. At the top of the dark area there are numbers, look at the PB or FCC ID numbers. If they end in 9110 then you have an AT&T version of the phone, and the hardware will not work with T-Mobile's 3G service...

are you in the USA? you need to list your location. it is likely that you purchased the wrong version of the nexus one. there is an ATT version and a tmobile version. each only works with the proper 3G. so an ATT n1 on tmobile only gets edge, and vice versa. check which version you own.

[Q] no 4g or lte on stock or custom rom

So I've had this phone for almost a week now and I used to he able to get 4g LTE. But ever since I rooted it, I no longer get more than 3g. I now have bananacakes Holiraider 1.6 but I still don't get any higher than 3g. So my question is how do I get 4g and 4g lte. Oh and if anyone is using that custom Rom, is it possible to get faster than 1512? In his thread it shows you can clock it to 1566. Thanks a bunch I'm kinda new to this!

try dialing *#*#4636#*#* and see what your modem is set to, it should be GSM/WCDMA/LTE auto
you also may have an APN issue, verifiy that your APN is correct, perhaps contact your carrier for the correct APN settings for you phone and plan.

Well I'm now running a custom ROM. The apn is the same as other users and it does say the above. And yes I am in a 4G LTE area

Try doing the above and change to LTE only.
Then once you have 4G change it back. It should stay on 4G. I had to do this to get 4G on official rom.

Ok I just tried that but it wouldn't let me to switch it to LTE only. When I did, it switched it back to GSM/WCDMA/LTE auto. I'm just gonna relock my phone and set it back to the original stock rom and format my phone (yes I have the apps and stuff backed up). Because my actual mobile connection fluctuates on and off as well

the phone should be locked into the GSM/WCDMA/LTE setting. If you try to change it from that setting it just returns back. The phone will get instructions from the carrier's base station to tell it whether to be on LTE or just 4G/3G. Using *#*#4636#*#* under phone information, what is listed as the Network type?

It is locked in GSM/WCDM/LTE auto.

above that option it should tell you the network type. it is about half way between the "run ping test" button and the "Set Preferred Network type" option. Need to know what it says there.

Oh ok I see what you mean, it says HSDPA

make sure that you are in a active LTE area. toggle the radio off and on. the network type should change to LTE if it is available. remember that if you make a phone call your phone will drop back to just 4g/3g and it might take a second for it to switch back to LTE.

I live in Los Angeles so I'm like in the center of the LTE center in Southern California. But for some reason my phone won't get anything higher than 3G, and my actual cellphone reception toggles on and off randomly too.

It worked before. For the first 3 days atleast. And now all of the sudden it wouldn't work, so I rooted it and installed a custom ROM

Try one of WildChilds custom ROMS. LTE works on both and they're tailored to US users.

if the problem arised before you rooted and rom'd the phone I doubt the rom is the problem. there is always the chance that you have a bad radio.

That's what I'm thinking... What would I do about this?

i would verify your sim with another 4gLTE phone and vice versa.

Hrm... So it could be a Sim card problem eh? Unfortunately there are no other LTE devices for me to get a hold of... Would this be the only way?

it could be. i hope you have pulled battery/sim and then rebooted already. you can verify your phone with a known good sim and verify your sim with a known good phone. I would try your local at&t store. they might be able to help.

I have done it many times . Yeah I'm actually going to head over to the at&t store in a few minutes, I'll keep you posted. Thank you so much for your help! rft3ch!

I will be replacing my phone. I replaced the sim card and that wasn't the problem . The rep said that someone else came in with the same problem as well.

[Q] Can Lumia 928 be used overseas ?

Hello all- I have not found a definitive answer so will post my question here as well. I have a chance to get a Lumia 928 (Verizon) but would like to know if I can use it in New Zealand with my Vodafone SIM. I am not sure if there will be limitations such as maps, etc.. not working.
Cheers for any help, LL13- :victory:

LTE will not work in any country besides the US. Aside from that the 928 shouldn't have any issues with taking a different SIM, as all 928s are SIM unlocked when they shipped from the factory. Before you leave though, I highly recommend you download access point via sysapp pusher in the marketplace/store. Sysapp will check for any and all OEM apps that need updating.

The one warning I would give you with the 928 is that the APN settings are a little messed up, and you may need to play around with it a bit to get them to work. My experience (using the 928 on AT&T and T-Mobile in the US) is that you need to manually set the APN settings, even when Nokia Access Point says that the SIM settings are activated. You can usually get data fine, but MMS's don't work properly if you don't manually set the APN
If possible, avoid doing it with Nokia Access Point, because if you do you will lose the ability to use LTE when you get back on Verizon until you do a hard reset (you can't recover the appropriate Verizon LTE APN settings - it will only connect to CDMA 3g). Now that GDR2 is out, you can seemingly manually set the APN's in the Cellular menu of settings, so try using that first and if it fails, copy the correct APN settings into a new Access Point APN, then manually activate it. This has fixed my issue every time, but again, necessitated a hard reset / wipe of the phone to use on Verizon's LTE network.

Cheers for that information AR...
I can enter those settings manually, I've got them memorised :silly:
Cheers again, LL13- :good:

Wow very confusing topic, I mean the process of finding out whether data/mms will work outside of Verizon US, it seems it can not. Too bad as it's a beauty of a phone.

Its not that quite confusing.
LTE is only good for the country it was released in. The international LTE bandplan is different for every country, none of them match up. For using a CDMA carrier, switching to them will require a SIM (there isn't any way to flash the settings onto the phone yet for those providers who don't yet have LTE without it being official from Nokia) so its kinda a dead end.
If your going to a GSM provider, just insert your SIM and manually add the settings for data and mms. You can use Access Point if you don't intend on using Verizon's LTE.

That makes me a bit more comfortable, cheers for that information thals1992 !!
It seems that the main issue would be with the LTE which would not be a problem since I am not even sure what it is !! I believe it may have to do with 4G or fast download speeds but there is no 4G in my town anyway.
I saw one post on another forum saying that some 928's had no way to add/edit APN settings, etc...
Each post and person seems to have a different experience, but if I can simply get a 3G data connection and normal use I would be happy.
I may just go for it then.

When you travel abroad and use the phone on a GSM carrier you will get data up to HSPA+, unless the carrier happens to share Verizons LTE band. The issue with Verizon LTE after you have used another APN is that Access Point won't deactivate all the APN settings,and since Verizon doesn't have dedicated APN data settings, it doesn't override properly and connect toVZW LTE properly without a hard reset.
The 928 has a CDMA radio as well as a fully unlocked GSM radio

I have also experienced this loss of Verizon LTE after using the Nokia Access Point app and foreign SIM in Europe. Does anyone know if there is a way to get LTE back other then hard resetting the phone?

a hard reset is required as the access point app changes the LTE settings and can't change it back completely.

I can get dataconnection in sweden, and i can install the nokia app for changing APN, and i can change the APN manually too, but i cannot get MMS to work, nor in or out.
any suggestions? i talked to my carrier and they helped me with the right info, but nada.

Try limiting the connection to 3G or 2G. T-Mobile users reported this as a workaround.

trying to connect Samsung tab s2 (smt819) to vodafone 4g no joy

Hi there, well I got this new tablet and its pretty good apart from I cant get vodafone 4g to work on it... I got a 4g data plan put the sim in and only got H+ max... when I put the sim in it said due to sim change/new sim will need to update settings but as the device doesnt do it automatically will have to do manually but vodafone doesnt show any settings info on their site when I clicked on the link... spoke with vodafone a few times and so far no luck even though they say the tablet supports 4g and they support the tab... now I swapped my phones sim with the tab sim and at first my phone wouldnt do 4g either till I installed the settings they texted me across (phone supports auto settings) and then the data card got 4g... but the phone card in the tab didnt and did the same message saying get the settings which I cant do as they are not on the vodafone site... anyone have any idea? many thanks

ok so after a lot of searching it appears it might be the fact that the tablet I ordered does not in fact come with b20 (800dd) which is what pretty much all the providers in the UK uses... I think this is hardware and not firmware related (is this correct) so I might have to return it... the tablet was advertised as having the 800 freq range so I either need to deal with H+ or return... ffs just set it all up too...

S10 4G bug?

has anyone noticed that the 4G on the S10 is quite buggy?
the speeds are extremely unstable, and sometimes completely unusable. (not a problem with the carrier, tried it on another phone and it's fine)
What I've noticed is that if it ever goes into medium power saving, 4G will stop working completely, it'll still show 4G, and i can still make calls, but no internet connection, even after exiting power saving mode. The only fix is I'd have to restart the phone for 4G to work again.
anyone have the same problem/ knows a fix?
I've read that I should do a factory reset, but I really want to avoid that, setting up the phone is time consuming.
Side note: battery life is not as good as expected, but that seems to be an issue for all exynos, not just me.

Same Problem here i unlock phone 4G shows but it tanke some time if i can use the Internet
Speed is Very slow and unstable

I am having connectivity problems as well. Keeps loosing the connection. I have to turn on airplane mode then turn it off all the time.

I don't have any problems with network connectivity, so far. In the link my result a moment ago: https://www.speedtest.net/my-result/a/4796337263
Hope you get some sensible connectivity soon. Cheers!

Same issue here! It was fine since I first received the device, but yesterday, I manually changed the network toggle to get better indoor signal. However, even after setting the toggle back to the original setting the LTE and data service kept dropping out. I tried manually toggling, switching network bands, etc... but nothing worked. It just keeps dropping data service.
I just hard reset the phone moments ago, and will update accordingly!

Update - Even after a network reset and hard reset it still dropped to Edge data a few times. However, after the last hour or so, it has locked back on to LTE+ and is holding strong. Seriously hope this is a software bug and not a bum radio chipset or antenna.

I'm on tmobile and my data is horrible in certain and what's weird I have all bars.

not sure if i should say that its good to know I didn't get a dud.
but man, samsung needs to get their sh*t together, this is not acceptable for a flagship phone.
looks like i'll have to do a factory reset soon.

I'm on tmo as well. I have a feeling it's just jacked up radio software. I did some more tweaking and went into band settings *#BAND# on the dialer and disabled all the LTE bands that aren't used by TMO and that seems to have helped as well. It think this issue is congruent to the known issue with Sprint devices trying to connect to incorrect bands. I haven't used it out and about yet, but it definitely helped my phone stay latched on to LTE from my home. Additionally, when it does drop to HSPA, it doesn't get stuck like it used to.
I recommend tweaking the band setting before doing a hard reset.

Update - still doesn't fix the problem. Pains me to say it, but I'm afraid I have a hardware issue. I'm going to try a sim card swap as a last ditch effort, but will also seek an exchange as well just to get ahead of the problem.

This shortcut only works on Snapdragon version, do you have Snapdragon with 4G issue?

This code only runs on the Qualcomm chipset version. Oddly enough, my friend with the Exynos version has no problems, even though he's missing a couple of TMO bands for the US.

Yeah I have Exynos S10+ as well and it runs fine on T-mobile USA

This code is not working on SM-G9730 Qualcomm Hong Kong version. Any ideas?

Same problem here. I got the snapdragon US unlocked variant using here in Spain and compared with my old Google pixel, they do not have the same speed LTE connectivity even using the same SIM card. I tried to force using the 20 BAND (800 MHz) but I dont really know how. My galaxy s10 plus is using the BAND 3 so it does not let it picking the fastest possible band in my city. Any ideas? I also did think galaxy s10 plus US variant did not have 20 LTE band, but I checked it and realize it even does. One more question, what is the difference between 4G and LTE? Here in Spain all devices are running 4G, not seen any device running LTE, but my new samsung does. How can I switch it to 4g or LTE+? Thank you everyone boys.

just wondering if anyone has gotten the ASCA/ASC8 update and can report whether this problem is solved wit firmware update?

Bands matter depending on where you are. Depending on your area, only specific bands will be used. However, some bands used, while not faulty, are easily interfered for some reason with cases or other obstructions like your hand. Most likely, Samsung is planning to give a large update considering signal direction. I would probably not factory reset if you have a lot of data, and the problem would probably come back.

I ended up having to send my device in to Samsung for analysis and repair. I'll keep everyone updated.

after ASC8 update, i think the problem has been solved, havent noticed any problems so far
