No LTE, poor signal strength.... - Samsung Galaxy S9+ Questions & Answers

Hey guys...
I've been using a rooted G965F UAE S9+ on ATT prepaid... I've been having issues with poor signal strength. I upgraded from the stock nougat to pie g965fxxu4cse3, baseband 965fxxu4cse1 but this didn't help... I thought it was the service provider since I moved from Philadelphia to Mobile, AL, so I switched to tmobile and this helped a bit but I still have problems. I went to the tmobile store and they told me that my device is unidentified on their network and showing that I get 2g, while other Samsung devices (s10) in the store have full bars and lte. I feel like I had the same issues with my S7 edge duos... My question is, does the international phone that I have use weaker signal strength? Do I have the wrong baseband version? Any other ideas on how I can identify and fix the problem? I like using a rooted device so I'm not going to switch to an American version and I really don't like the other phones out there in comparison so any help would be greatly appreciated!! Thanks.

Do you have the correct APN settings for AT&T or T-Mobile?

Thanks for the reply! I believe I have the correct APN settings and this was verified by the store staff...

I was hoping I could flash the baseband for the g965u1 variant but it didn't work.... ODIN froze at "verifying file."

The APN looks good. Might be a baseband issue. Someone with deeper flashing experience than me might need to chime in here.

[Q] So I can know for sure - Springboard, ICS, and GSM voice?

I've really been considering a T-Mobile Springboard lately, but getting it banks on the assumption that flashing ICS on it would unlock GSM voice/text, and let me use the Springboard as a phone by putting my T-Mobile USA SIM in it.
One person in the general discussion topic basically said that it would work, but I just want to make sure before I plop $300 on a device when I could have gotten a different tablet instead (likely the HTC Flyer 3G at ~$450). I'm assuming I'd have to delete the /efs folder to keep T-Mobile from picking up the IMEI and blocking the SIM with the voice plan on it, correct? And would I be expecting slower data speeds after flashing? I'm not concerned about that part, just wondering.
EDIT: And as the title suggests, I'm talking about the T-Mobile Springboard, not the international Huawei Mediapad.
ICS and Phone work for my Springboard
I have a T-Mobile Springboard that I purchased on ebay. I just flashed the ICS in place of stock T-Mobile a couple of days ago. I had a T-mobile SIM for prepaid Mobile broadband, and got an error announcement when trying to use the new phone feature.
I called T-mobile and had my plan changed to a pay by the day plan just to check the phone functionality. It works great! I have only used it as speakerphone, but assume you could pair it with a Bluetooth headset.
Note - the IMEI from the Springboard will not work to set up a voice and data plan. T-Mobile rep said it was invalid for a voice plan and asked for another IMEI off another GSM phone. If you already have a SIM and plan for a smartphone you should be able to plug it in and go I expect.
Sweet, good to know, think I may have just decided on a tablet. And yeah, I'd be swapping the SIM in my current T-Mobile phone in and out for phone/data capability, not a separate plan for it.
Yes it works great. Well worth it wont find a better deal
I have a SIM card on T-Mobile for the Value Talk+Text+2GB. From what I read here, this will this work fine for the tablet with gsm voice?
I have the same plan, and the voice does work. However, I am so far not able to get both voice and data to work on the plan. I really bought the thing to use over wifi but registered a T-mobile account to try out the phone feature and to allow me the ability to request a SIM unlock.
Just realized I had turned network data off and hadn't verified all three services worked together - so far the answer for me is no. I turned wifi off and network data on, and now I currently can get voice and text working but not internet over T-mobile network. Trying to open a webpage currently just sends me to the my.t-mobile login page.
I called T-mobile support and was told that since it is a tablet, they would not support both voice and data for it.
Is anyone else having luck with getting both voice and data over t-mobile network?

Areas like user/pass/server should be blank (ie: nothing at all, anything <not set> should be blank)
The other red highlighted areas that you put down don't really matter. If it still doesn't work after that then I dunno... it has to be something else.
I wish we could get a conclusive yes or no to whether or not this damn tablet works just like a smart phone (just like HTC Flyer 3G) so I can decide which stinking one to get.
so eager to get the asnwer too
Seems there is no absoluet yes or no....consfusing....

I'm guessing, since that's the folder I see mentioned in other phone-tablet topics to keep the carrier from catching on.

Is there no ramification (on the phones software) for deleting that folder? Will the carrier just see it as a generic device?

I don't believe so, but you obviously want to back it up elsewhere anyway just in case, and I believe that's the idea of it (carrier unable to detect IMEI and therefore unable to restrict you in some way based off of it).
I don't have any good news on this. I took another run at T-mobile customer service today and was again told that this device was not permitted to have both voice/text plus internet. I can have voice and text on the 2$/day plan or I can have data and no voice on a tablet mobile broadband plan.
T-mobile said "Tablets are not phones!" I demonstrated while on the phone with the rep my ability to make calls and text with the Mediapad.
I argued every logical angle I could conceive, and the rep agreed with any logic I presented for having the 3 services available all at once for tablets. While we were in complete agreement that it would be 'nice' if it would work, he could not suggest a plan that would allow for 'talk text web' on this device.
The rep did say that T-mobile was 'working on' a new plan to allow for these tablets with phone capabilities.

What you should do is just ask for the smartphone value 500 plan.
500 mins, unlimited text, 2GB of data for $49/month
Once that's on your sim or whatever, try to access everything. Don't ask for a plan that doesn't exist.

Could try, but I expect then I would just be out $50 and still only get phone and text. Two different T-mobile reps have said they have no plan that will allow for talk, text, and web for this device.
My experience is as a new customer as my current phone is on AT&T. Possible someone who is already on a T-mobile smartphone plan can get it to work with their existing SIM.
I am quite happy with this device as wifi only for now. Was mostly just curious if I could get the phone function to work. Working now to get a SIM unlock so I can try the thing with AT&T.
Just got my springboard tonight. First thing I installed the rooted ICS leak. Popped in my TMobile Monthly4g Sim (on $30 5gb Walmart plan) and I have phone and SMS but no data. Apps time out and browser redirect to my.TMobile.com... Really want to get this working... Any ideas guys? I'm willing to test. my next step may be a straighttalk byod Sim... If that doesn't work I'll have to move to AT&T and the galaxy tab plus

I doubt it would work on a ghetto plan like that anyways (isn't that prepaid also?). Wish someone would try a real plan.

Rogers samsung Galaxy S3 I747M APN Issue

Hi Everyone,
I am new to Android. I just got a galaxy S3 from Rogers and I unlocked it. I am now using it under Fido. I have 2 major issues that maybe the forum can help me out.
1) when I got the phone the build in settings for Fido LTE did not work so I added my own APN and it now works. The problem is that is I take out the battery or shut off and restart the phone I lose the APN settings. According to Samsung the Apn is fixed to rogers and you cannot add any new APN. Is there a work around to allow me to store more APN as I travel a lot ?
2) I have visual voice mail. since this is a rogers phone, the visual voice mail program is built into the phone. So when I download the visual voice mail app for fido it tells me that there is conflict with another program in the system. Is there a way to get rid of the visual voice mail app for rogers so my visual voice mail for fido will work ?

This should help out with data, tethering and mms.
Not sure about the visual voicemail though cause I dont have that service.
i have the same APN issue with my rogers S3 on at&t, I cant change the apn type, i only get 3 options internet, mms, or internet and mms. anyway to change this ? or do i have to flash a at&t rom or CM10 on it ?

Your best bet is to create a new APN and use that. After you have created the required APN, just select it and it should work fine.

What did you tried, and what happened? Is the plan you are trying to use on GSM network (like AT&T and T-Mobile)? If so, simply putting in the sim card and reboot the phone, the calls will work. You will have to change APN setting to get on the mobile data network.

[Q] S5. Switched from verizon to tmobile. Questions

Hi;
I just switched to tmobile from verizon.
Using my verizon galaxy S5. Unrooted
1 )I have seen this setting in this forum for APN:
APN Type should be default,mms/supl,dun
My store set mine without the "dun" at the end of the string. Will/what difference would this make?
2) Is there any way to activate the wifi calling feature on my phone or is it a hardware change?
3) I used to use Foxfi for hot spot tethering with no limits. Is there a way to activate it to work on tmobile?
Thank you.
T-Mobile and AT&T utilize the GSM technology while Verizon and Sprint use the CDMA technology. Their respective devices are also different in hardware. So as far as I know you won't be able to use your CDMA phone on a GSM network. Someone correct me if I'm wrong please!

Yes.

For what its worth, Verizon devices (not all of them, just some. Its hit or miss depending on the device) for some reason, tend to have GSM radios in them in addition to the CDMA ones. I remember though that the Verizon devices wouldn't work on T-Mobile 4G (HSPA+) due to the 1700 MHZ band. But I believe the refarming of the towers made all 4G (HSPA+) go to 1900MHZ, which the Verizon module supports. So that is why its working.
I forget what "dun" means in the APN setting. As you can see, commodor doesn't have it, mine does. Does it make a difference, prolly a very slight, specific scenario difference. Quick search shows that "dun" stands for Dial-Up Networking. I hated Dial-Up so I wouldn't worry that your's doesn't have that specified
To get WiFi calling, you would need to flash a T-Mobile ROM, note, I said ROM, NOT kernel. I believe all the WiFi calling stuff is in the ROM and lib files. So a ROM might work. I don't think flashing the kernel from T-Mobile would harm the device, if they weren't compatible, you would just get a non-booting device. It would stay at the samsung screen. Which all you'd have to do to fix is flash a VZW S5 kernel.
There are many methods to make Tethering work, many require root. I don't think tethering is possible without root. Also, with these methods, it will still use your data, whether its a tiered plan or not, you will still accumulate data usage.
Thank you.
