Can't get my Tmobile sim to work in my Tmobile Streak 7, need help!

Just purchased a used Tmobile dell streak 7. It is stock and has been reset to all factory settings. The wifi works and everything looks to be ok. I got a tmobile sim card with a 2gig mobile broad band data plan. I know the sim is good and activiated because it works just fine in my buddy's stock tmobile g slate. When I insert it in the streak it recognizes the sim card and restarts but I cant use the interent via the sim. I went through the settings like the user manual says and turned off the wifi, I searched for networks and selected "Tmobile", then it says "registered on network" but no 4g/3g icon show up in the right corner. I just get the wireless bars with an x? I am new to tablets so maybe there is something that I am missing? I need to figure this out today because the guy I purchased it from gave me 24 hrs to try to get it working or I could just get my money back. Any help would be appreciated. Thanks, Jared

anyone? Im running out of time here... I tried my at&t sim out of my iphone and it instantly wanted a "special code" which was expected. Could somebody have tried to enter a code too many times while using a tmobile sim card and somehow locked out the tmobile capability?

You need to call T-Mobile customer service, or go into a T-Mobile store, and have them activate the SIM card for the tablet. They have to be tied together.
EDIT: Activate it for THAT specific tablet.

is that true for all tmobile tablets because the sim works fine in a tmobile g slate and the card was not tied to that tablet in any way, but I will try

It just occurred to me that the wireless bars with an x over it could also means that someone has removed or renamed the phone.apk & telephony.apk. I don't have a t-mobile DS 7 so I cannot be certain of this, but you can check it out for yourself. Use a file manager program and go to the directory /system/app and look to see if phone.apk and telephony.apk has been renamed or removed. I have the DS7 wifi edition, and I removed these 2 app so that the DS7 does not drain the battery. My DS7 has the wireless bars with an x over it because I have removed those 2 app.

If ya need those files let me know and ill put em up..im stock t-mo rooted...
just got my streak and ill be around now

[Q] Verizon LG G2 GSM Support

Hello All,
I have been thinking about traveling to Japan this coming year; I have looked at Verizon's International plan, and it seems like they are very pricey.
I have heard that the VS980 has GSM support, with no LTE, which is fine. I have looked into the h20 network, as they have exceptional prices for their international plan.
I have googled it and have gotten mixed answers, so I came here. I have a h20 sim card, and it pulls the APNs, but does not get any service. Is it that I am using a custom rom?
Thanks for the help in advance! :laugh:

aerial irrntsrt
Please someone answer this. I'm in a similar boat.
I'm on the stock verizon ROM. I have a Piranha mobile sim card. I am testing the setup in the US to verify it works. It connects to the T-mobile/Piranha voice and sms network, but data is not working.
Their setup instructions call for setting the apn to openroamer.com, but no mention on the mnc or the mcc values. If I just set the apn to openroamer.com I'm able to save and select it, but as soon as I change the mnc or mcc values to t-mobile the apn disappears after I save. Do I need to set the mnc and mcc values to something specific? I tried to track down exactly what they do, with no luck.
I see mention in another thread that Verizon locks the phones to be unable to connect to other US domestic networks. They also mention that once I'm overseas I'll be fine. I'm skeptical.
I was thinking of going to the t-mobile store to see if I could borrow a sim card to confirm it's a firmware issue. I would rather not root at this point. Any other courses of action?
Thanks for shedding any light.

It turns out to be a activation error for me, after I correctly activated the sim, it worked! (silly me!)
For your problem, I looked on your carriers website/ help websites and there are no values except the APN.
You might need a data plan active. I would try using other carriers, because for me the h20 sim worked with data.
Verizon has no control over what network you go on either, FCC has a couple laws that prevent from Verizon doing that except exclude the hardware needed to connect to other networks.
Sorry I could not help.

I popped my Aio Wireless (AT&T) SIM from my Nexus 4 into my G2 and after a little APN tweaking I had HSPA+ working with no issues. It is my understanding if you have AT&T Band 4 LTE (limited markets) and the correct service providor, it will even connect 4G/LTE on AT&T networks. I swapped my Verizon SIM back in and removed the APN's and all was well on Verizon again. I am stock (KitKat) and rooted with only a few few Xposed modules installed, no custom ROM.

It sounds like, from reading the posts above, the Verizon LG-G2 IS a World Phone and should function straight on from stock on a UK provider like Three just by purchasing a sim and plugging it in then configuring the APN settings !
The problem is that when my Susan went just this morning to a Three store in London, the guy there told her that her Verizon LG-G2 was LOCKED to Verizon network only, and that she would have to do something like obtain an unlock code because the phone would not work on any other provider until she did that.
Verizon's International folks told us earlier that the phone would work fine, given GSM frequency issue restrictions, overseas and there was no need for any UnLock proceedure or code.
Does she just need to find a competent tech at a different Three store ?
Or is she going to be unable to play Ingress the whole two weeks she is over there in England and Scotland ?

Update...both Three and Vodaphone folks in London have now told her that the Verizon LG-G2 is carrier locked and cannot be used without Verizon unlocking it on any other network. So, Verizon was wrong and she is limited to WiFi only for the next two weeks ?

No global mode Verizon phones are carrier locked.

It is very odd. We tried it on a T-Mobile sim over here before she left, I am pretty sure, and it just worked. Still, over in London Three & Vodaphone say it is locked and useless on their networks and their sims don't work.
Maybe it is subsidy-locked ?
Maybe they just didn't set the APN and data settings right at the stores ?

Tmobile Note 4 on At&t losing lte

So I put my SIM in from my g3 (which was T-Mobile and getting great lte) and phone was working fine then for some reason reverts to 4g and no lte. Check my account online and my phones imei shows up as an old blackberry which downgrades my plan automatically.
I can stick SIM back in old phone get lte, switch again and it reverts. Called and customer service can't seem to help. Anyone else with T-Mobile note on att having issues ?

I have been having a different issue. Every couple of days, I would loose all T network connection as the APN "ATT Phone" would become unselected for a as of yet undetermined reason. If I select it, everything works just fine (include LTE) till it unselects itself a day or two later. I cannot determine the cause.
If I look on my account it shown some "dumb" phone whereas I used to have a Note 2. I do get LTE. I use these APN setting, which seem to show up as default when I press the reset on the APN menu:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
See if these are the setting your SIM selects. If not, you can try unselecting "ATT Phone", change it and select it after saving. But perhaps you need a new SIM which T should be happy to give (or maybe it is a couple of $) you if you visit a store and say you lost your phone and the sim.

Thanks for the input. Yes I have tried deleting apn settings and adding the ones like you listed. It didn't help. Get 4g but no lte. Went to att they pretty much just said too bad it's not our problem cause it's a T-Mobile phone.

So far no issues running it in Manhattan for a couple weeks - I can't tell the difference between this, my OnePlus One, and my old AT&T Note 3 - all using the same AT&T SIM.
I did get some slow data speeds while in Williamsburg last weekend, but my wife's AT&T iPhone 6 had the same issues so I don't think it was a phone issue.

Oh okay. I don't know why mine is having this issue. Have used several T-Mobile phones on att without issue

Sorry to say it appears the Note 4 is polled or "phones home" and immediately shows it's non-approved IMEI. When I change the SIM from my T-Mobile Note 4 to my ATT Note 2 the MyATT page almost instantly changes from BlackBerry7100 to "Smartphone". Not sure what to do because it'll surely cost my LTE speed.

I've been using a T-Mobile Note 4 on AT&T since the week it launched without these problems. I have a feeling I'm jinxing myself or that it's only a matter of time before it does happen. What's weird to me is that on the AT&T page it shows I still have my old LG G3.
Are you guys using custom ROMS or Kernels or anything? I have pretty much rooted from day one and froze a bunch of stuff and immediately got rid of the Carrier IQ.

Well let me chime in. I never got lte on the note 4 until I got tired of slower speeds haha. I had an iPhone so I went to at$t to get another sim card but brought my s3 so they wouldn't know of the note 4. Problem I think was putting it straight into the note 4 and not settle into the s3 first and get all required info. So I was without LTE for a while until I decided to try again for it. So I called at$t and told them I was not getting LTE on my phone 5s so they changed the imei # to the one for the 5s. Still didn't get any lte so I went to an at$t store when they said to pick up a new sim. I used the iPhone probably for about an hour and got LTE. So from that point I put the nano sim into the note 4 and now I've been getting lte for over two weeks and great signal coverage. On my account it says I'm using a dumb phone but when I go into upgrade options it says I'm on an iPhone 5s.

And yes I'm using a nano sim not the usual micro sim

[Q] Straight Tall APN issue with SM-910T

So I recently got a T-Mobile Samsung Galaxy Note 4. As we know, it's unlocked 100% without any special root methods or entering in codes into the dial pad. With that being said, I popped in an LTE Straight Talk SIM card, transferred my old number to the new SIM and configured the APN and for a long while it was working fine with no issues. Then out of the blue, I had no data. It absolutely quit without warning. I go to check the APN settings I had previously and they were gone. I had redone everything and saved the settings. However, when I go back out a menu, no Straight Talk APN. I did the same thing again....and once again no APN settings. Just the default T-Mobile LTE APN.
So I'm at a loss. It was working fine previously and now I cannot set APN settings. I have reset the phone more than once (reluctantly). Any thoughts? Any help would be appreciated since I'm paying those bastards $45 and some change a month for service I cannot get. Also as a note, I can receive and send text messages with no problem. Calling number results in "you are not registered on a network," but I know the fix for that.

Try setting the APN with this app https://play.google.com/store/apps/details?id=com.tracfone.straighttalk.stdatasettings

Sounds like your phone got black listed. Did you buy it from Tmobile? If you bought it from some one else it was either a stolen phone or the previous own stopped paying for it.

I had bought the phone from a local gas station owner (who had 2 other T-Mobile phones with him). It was working while he showed me the phone (he had gotten several text message and Facebook updates). He then reset it. I bought a Straight Talk SIM kit and went to work. I had working data until the next day. I had played around with some more internal settings, like updating the touch sensitivity and more. Everything was working until I refreshed the Wi-Fi antennae. Don't think that would have anything to do with the 4G/LTE radios or regular antennas. Overall, it was working, so I don't see how it could just magically stop.

If he bought the phone on a lease from T-MOBILE and never fully paid it off T-Mobile would black list it. Or if he sold you a lost\stolen phone.
You can contact T-Mobile or check the IMEI on one of those checker sights to see if it has been blacklisted.

You can check to see if you're blacklisted by visiting the T-Mobile website and using their IMEI checker. If you're blacklisted you would not be able to place calls. I will attach sample AT&T APN that works for me. I'm on Cricket and not StraightTalk but it may work for you.

For all who helped out on this post, THANK YOU! I figured what my issue was. SIM card is fine and the data settings work as long I don't configure the MCC & MNC settings. Changing the MNC from 260 to 410 is what caused my saved APN to disappear. Not sure why that happens, but if any of you have an idea of why, direct me to the thread that explains this or if you know, quote this reply. And another thing, I am able to send texts and make calls, but due to the location I was in, texts sent at half the speed of smell and making a call was impossible due the phone claiming I was "not on a registered network" even though ST is a network (duh). I have no service issues on my Note 3 N900A when I that. Anyone think it could be because AT&T's device antennas differ from that of a T-Mobile Note 4? Personally, I don't think they would since they are both GSM and operate on the same bands (I would think), even though the Note 4 has "newer" technology. Not really worried about data, texts or calls since I have Wi-Fi in said location.
Again, thanks to those that helped me out. And, again, if anyone has any ideas to the information said above, by all means give your say or direct me to where there is substantial info.

Help on getting phone working on straight talk.

Long story short. I was using a Verizon branded note 2 on straight talk when my contract ended with verizon. I grew tired of the phone and purchased the blu vivo xl from amazon a few days ago. Now I know that my sim in my Verizon wouldn't work on the blu phone because it's not compatible.
So I went on chat to switch my Verizon sim to an att sim from the same byop package (which also came with a tmobile sim) They said that it could take anywhere from an hour to 2 days to convert over, and that I'll know when it happens because my note 2 will stop working. Sure enough it stopped and a bit later my blu phone started getting a signal and 4G icon.
However, it was in and out all night and since then I haven't got it back. Frustrated, I then switched it to the tmobile sim. I get the 4G lte icon and arrows move up and down. My signal goes from 2/4 bars to 3/4 bars. Now I'm thinking good that's more than what att was able to do. Wrong. Well not completely.
I can send a text and my wife will get it. Not really slow but not normal. She'll reply and I can receive it. But I can't access the internet, and I can't call or receive calls. Went on chat they gave me apns to input and still nothing. I still get 4G icon and I still get service.
I really like this phone but this transition has been really draining.
Thanks you for your help.

I have no idea, I had a really smooth transition activating it onto metro. Maybe you just have spotty coverage with straight talk in your area? I'll try looking for more info

Correct. The phone is loaded with apns that matched what they gave me. The straight talk for att and tmobile.
So as an update, I bought a tmobile sim, (not straight talk this time) the phone received texts from tmobile for this and that. I have good signal as indicated from the bars. 4G lte icon is on (but no data due to not having a tmobile account, but the sim is allowed 30 texts and 30 minutes of talk time until I get one)
The problem that is persisting is that I cannot make a call. I'll dial any number between my wife's, friends even my own and it just gets stuck on dialing. No operator or anything just blank. It's flashing "dialing..." but it won't actually go and do anything.
I contacted blu, and they gave me the same apns that I used and assured me that it should work on straight talk. But yet still nothing. I contacted blu again after I got the tmobile sim. I'm awaiting an answer on that before I proclaim the phone a dud and exchange with amazon.com.

StraightTalk is owned and operated by Tracfone. I went through more blood pressure pills dealing with them than almost any other corporation. Best bet? Switch to almost any other carrier. I use Airvoice, but there are a BUNCH of others out there with no contract, pay-as-you-go programs. Truly, there are better deals out there than StraightTalk/Tracfone.

You are having issues (I think) because different phones available through Straight Talk work on different networks. They ask for your zip code and then show you phones from different networks that will work in your area. If you use a SIM card you are AT&T or T-Mobile. Sprint and Verizon use CDMA. Check coverage maps. This will explain why your coverage is spotty now. There is a list floating around out there that shows which networks use what phones and so on for Straight Talk. Once you put the SIM card in the phone, it picks up whatever network is available in your area. If it's a network that doesn't have great coverage where you are, service is diminished.
