Samsung Tab 3 Deleting Default APN - Galaxy Tab 3 Q&A, Help & Troubleshooting

I am using custom/dedicated APN from ATT and Tmobile for work. I have 3 tab 7.0 inch from ATT (SM-T217A). I am testing this before purchasing more.
All three units are from ATT. I do not have any tablets from T-mobile currently. On ATT APN I2gold, I have set it up and it work as expected, however the tablet switches back to default ATT broadband APN often like every 10 minutes, not suitable for the business. Unlocking my SM-T217A and using it on Tmobile with Tmobile custom APN that works and it does not change it always stays on the dedicated APN(b2b.tmobile.com) which is what my goal is with ATT and ATT device.
To summarize, ATT Device with Tmobile Sim works on APN I input, I believe Tmobile Device on ATT Sim Card would have the same result.
Is is possible to delete default APN from ATT on ATT device? I just want to get rid off ATT Broadband APN and their Activation APN.

Found a solution deeply searching into it

It seems to work for me.

Gsm vs lte

I have never used gsm phones so i got this galaxy nexus from google play and i plan to root and flash custom rom with tmobile 4g prepaid plan. my question is:
do i have to enter apn for tmobile prepaid everytime i flash new rom ? or does it work like cdma where u flash any custom rom and it automatically connect to my carrier?
thanks a bunch in advance
Depending on the carrier, APNs will usually load by default just fine off of the SIM card. If the APN doesn't show up, just go into: Settings > Mobile networks > Access Point Names > "menu" > "Reset to default" .
Some carriers (usually MVNO's) require a specific APN that may not automatically set itself. Especially for MMS.
i have att but all i ever do is just put the sim in and it works
unless the apn is different for a prepaid plan from tmo you shouldnt have to do anything else either. my coworker has tmo and he has to call and tell them if he is using windows phone, android or other data....because tmo apparently thinks packets differ
Just put in the sim, it will load the proper settings. Flashing roms won't matter.
Unless T-Mobile pre paid has some weird issue I've not heard about.

Please help LTE stopped working not sure why!!!!

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

appreciated!
I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?

Korean KT Samsung Note 4 is not getting 4G/LTE. It is only getting 3G on ATT Go Phone SIM Plan. At one time on a Family Talk Plan it was getting 4G/LTE. I tried talking to ATT Tech Support but all they did was try different APN Settings and did not work. I did notice the APN Settings would not stick to the NXTGENPHONE APN (Flashed a message stating unstable Network) and always automatically switched back to the Cingular 410 APN. I already paid $70 for the GoPhone Plan. Can anyone please help me get 4G/LTE on the GoPhone Plan? I tried different modes in the Hidden Menu. One of the LTE Modes did give me LTE and gave really fast data but all my cell phone bars went to zero. Is there any other settings or the Hidden Menu or APN Configurations that will work? TIA.
