Weird situation: No service after installing Lovebabyjing ROM

The reason I say this is a weird situation is because I'm actually using an old Suncom SIM card. My girlfriend's phone finally died after going through numerous drops/abuse for the past few years, so I was going to give her my old Dash. Now, the official ROM does that "network is locked" thing, so I figured I would a custom ROM. Well, I was able to start up the phone successfully and use it fully with the Suncom SIM inserted, but it does not find the T-mobile signal.
Is there a way around this, or is she going to have to go to T-mobile and have her SIM converted over to a T-mobile one?

is your phone sim unlock? In order to use other provider< you phone must be sim unlocked>
good luck

That's the thing though, it's not being used by a DIFFERENT provider, but actually by the SAME provider. The only problem is that the SIM card is from the old company before the two merged, so I'm guessing that makes a difference.

Maybe as we have company's that use same carrier yet the sims can't be used without unlock phone.
Eg: BT, Asda both use Vodaphone yet can't have a Vodaphone or Asda SIM in a BT phone without unlock...

[Q] GoPhone... Will a Glide work?

It seems that the Glide is only an AT&T-branded phone. Has anyone used one with GoPhone? Thought about picking up an unlocked one on eBay but I don't want to encounter the same "Invalid SIM card" issue I encounter when I put my GoPhone SIM card into my unlocked AT&T-sourced Skyrocket. Thanks for any info!

I can't say for certain, but I don't see why not. I use my phone with the T-Mobile monthly 4g plan and everything works fine. I do however, only have an EDGE/2g speed data wise due to the frequencies, but the phone was designed for AT&T so that wouldn't be a problem for you.

Appreciate the reply, narume. I think that the issue arises from this:

Let me know if you ever get that working.
What i THINK is that any phone that comes out of AT&T's clutches are in their system (both imei and with carrier iq) so once it you pop a sim into it and the information is matched to a device in their system they know what can and can't be allowed for the device. With international devices they don't have those IMEIs (which is why they always want the imei from you so they can match it in their system)
Your note is international...they can't "match or track it" so to their system it's just another random dumb phone
Your skyrocket is a known LTE/HSPA+ device to the system so it says no cheap data for you

So...assuming that this reasoning is correct, if AT&T knows that it's their phone they will have blocked its IMEI from being able to access data through GoPhone. And I would need 3G access in order to use it on my MicroCell. Anybody...?

Any at&t phones will work on go phone, and you can use a microcell as well, your phone still uses the 3/4G signal to connect for calls and texts. Also to get data to work for pictures, and mms you just need to call them and they will send you the apns, my nephew in law has an atrix 2 on a microcell with pic messaging working great. They also have a solstice 2 (dump phone) on the microcell, both go phones.

If you're getting Invalid SIM, you may have a locked SIM card, something AT&T started doing with their prepaid a while back. New prepaid accounts have the SIM locked to the phone it was purchased with for ~3 months, after that I believe you have to either call or visit a store to have the lock removed.
Other than that, there's no reason it shouldn't work, but do remember that AT&T will see it as a smartphone. This means with their new prepaid plans, if you're using the 10 cents a minute plan you'll be unable to use data at all. If you're using one of the flat amounts per month, like the $25 or $50 plans, you'll need to purchase a data package (even though the $50 is SUPPOSED to include unlimited internet, smartphones aren't eligible).
I previously used a Motorola Flipside on AT&T's prepaid, before this change I was using the 10 cents a minute plan, with 1000 texts a month and buying a 500mb data package, then rolling over unused data each month with the 10mb package, and everything worked the same as if I was on postpaid - text, mms, internet, etc.

Thanks all! I'm 1½ months into my prepaid service. I'll check with AT&T after 3 months have passed and see if they can remove the SIM lock.

You might go ahead and call customer service anyway, who knows, you may get lucky. 3 months was what a rep told my friend a year or so ago, but that may have changed or may not have been the rule at all. Alternatively, you can go into a local store and purchase a new sim (or purchase one on ebay) and have them transfer your account over to it, just make sure they give you a regular sim and not a go-phone sim.
I just tested my captivate glide with the sim I was using in my flipside. It seems to read the sim just fine, though obviously I'm not still a prepaid customer so I can't make any real calls with it. I've also used it on a T-Mobile MyTouch 3G that was unlocked, briefly, when I was working on the flipside. Once you have the sim lock removed I expect you'll have no problems using it in any unlocked or AT&T locked phone.

If you use the 50 dollar plan and use the wap.cingular apn it will use data just set that up before you put in your sim, and do call they should unlock it for you, if not tell them you will be going to straight Talk at&t phones work locked on them since it's a part of at&t just ran by walmart.

I have two Glides that I activated in June. NEITHER WAS SIM-LOCKED, ever.
Both are the newer 4G SIM, not the older one that says 3G on it. Got em from eBay for about $2.75 each. Both were activated online, about 3 weeks apart.
The first one, I activated with an IMEI of a Glide that broke and was able to use the SIM on a different Glide and other phones, even the Pantech Burst and got 4G. I activated it as 10c plan, then moved it to the $50 unlimited.
The second one was activated with 0000... generic IMEI with the 10c plan, and just like the first one, I was able to use the SIM on any GSM phone I have in the house (and that's quite a few).
APN: wap.cingular - only the name is needed, no userid, etc.

Data blocked on phone sim when used on Tablet

Hi I wanted to know is there a bypass or trick or app to make the Internet work via a mobile sim.i wanted to use the t705 as a phone.the text works but data doesn't.
I get a message saying I can't use sim in a tablet.

What network you using chief?
if its Three, then its a bit awkward. you can either use a tablet sim which works but with no voice or texting, or you use a phone sim which uses voice and text but data dosent work.
i believe as the phone sim picks up the tablet as a "tethered device" (i think because the Tab-s identifies it to the sim somehow obviously as a tablet which three dosent seem to allow.)
frustrating as hell really.
i have used an EE sim in my tab -s and seems to work with voice, date and text. but cant speak for any other sims (ill have to try my VM staff sim and will report back)

I'm using three.so with ee it works fine . because with certain networks it works for a while then stops, I'm thinking shall I switch to ee.also is there some file that can be edited so the network recognise the device as a phone not tablet?

I've just discovered this very same problem, and had a very long conversation with three, who sadly aren't able to offer me anything!
I doubt that there will be anything that can spoof three in to thinking that their sim is being used in a phone, as it will likely mean providing a fake ime number etc, however, if there is a way, I'm all ears... If not, I guess I'm changing to EE

I roughly use 25gb of data so ee is to expensive for me.

Damn, thats a lot of data a month! Yeah, EE will definitely be no good for that. I ended up speaking to EE about the situation, they were of the same opinion as me, in that it seems crazy why you cant put your sim into what ever device you like and use it how you like. Consequently, they specifically told me that should I choose to put my EE phone sim into my tablet, they will be absolutely fine with it.
EE have themselves a new customer, three are a man down. Shame, as I actually really rated three. Hopefully they will see some sense in the near future

I had to leave O2 prior to joining three.... although most of the time it would show a full 3g signal, I'd get absolutely no data through most of the time... gift gaff just piggyback off their massively overcrowded network

I'm going to get it for a test drive.i left o2 ages ago because when I had a HTC hd 2 it didn't have a toggle to turn off data and my data would get used up eventually bard I explained to them how the phone was they didn't care later some developer made an app to toggle data off.

Gone are the days of sim swapping???

This is more of a general ATT thread, but it does relate to my note 4.....
I have a one plus one, and my note 4 and from day to day I want the flexibilty to swap phones as I see fit. It used to be move the sim, and you're good. Lately, I've see issues when I moved my sim from phone to phone.
The first was last week, I bought an alpha clone off of craigslist and voice would work, but data would not. I dropped it back into my one plus one, and same thing, no data. Went to an ATT store, and they did an IMEI swap on my account and all was well in the world. Years ago, the IMEI swap on the carrier system kinda just followed the phones and wasnt ever an 'official' thing...but now it seems it is. Any ideas on this, can I swap my IMEI online with ATT?
Obviously I did a search on it, and it takes me to the ATT website, but it looks more along the lines of swapping when you've made an official order, not just because you want to. Am I missing something?

Change the sim card. When I went from my g2 to a nexus 5 I swapped the sim when I got the nexus 5 in the mail and data wasn't working ect. I go down to the AT&T store and talk to the same girl who's actually on the ball there and we found out that if you have an ICIS sim card it won't work on phones they don't sell. Just get a generic lte sim and see if that fixes it. Good luck!

The Sims that are blue are lte Sims don't get the ones that are purple those are isis

Is that what ATT is giving out by default now? I have a nano sim (that i got for that nexus clone) and it works fine in my OPO. If I put it in my note 4, I only get 4G, not LTE, which I thought was odd. I can do as suggested, just want to make sure I understand first...

All att Sims are lte capable but the purple ones are softcard (isis) compatible, meaning they have the correct security features for the use of isis enabled devices

ok, so he meant isis above.
I think this is just a standard att LTE card...its orange...and it DOES work in my OPO, so I think that theory is out.

Call customer care and give them the imei of a phone that supports lte and have them add that and just not change the sim

The Isis/Softcard is a problem as described above, but there's also a "nextgenphone" feature that goes on your account with newer phones (along with your normal data feature) and newer phones are using that with a related APN so it could have something to do with that new feature. Haven't figured it out yet but I'm playing with the system & I'll post what I find. So far all my secure sims have changed phones fine. My Gear S gave me a couple problems but I'm not sure if they were related.

Interesting. When I went to another ATT store a few weeks ago to change to a nano sim, the rep changed some codes on my plan. I got this in an email:
DELETED MOBILESHAREVSL64VT
ADDED MOBILESHAREVP20
Last night I went to a different ATT store than usual, and found out they were just a partner (though you could never tell it) and he said there were a few wonky codes on my plan, one of which mentioned something about APNs...so maybe youre on to something. He was under the impression it was grandfathered though, so it was old. He could, of course be wrong.
He also tried his SIM (oh and I have a non-secure sim) in my one plus one from his moto x 2014 and it worked just fine. LTE and everything. He put my sim into his X, and got 4G only, no LTE.
So he swapped me back into a non-secure micro sim, just to try things out again, and I left the store with my one plus one working. I came home, dropped it into my Note 4, and got 4G only, no LTE. When I put it back into my OPO, I got a text message saying I needed a new sim to work with my phones new feature. Weird.

The original feature is just normal mobile share data but I'll have to look up the second one I haven't seen that in the system. What i know is that once you put your sim in a newer phone (last few months) the system auto adds that nextgen feature & you end up either needing a secure sim or have to put the correct imei on the account

So that sounds like its our culprit.
If i have a secure sim for my note 4....can I move that to my OPO? I've heard no, but I've also heard yes...

I have been swapping my Sim card that I got with my Note 4 with my Note 3 Nokia 1520 and my Gear S. I have had data act up but only with the Note 4. Everything else has worked fine. In the Note 4 what I have done is add the older apn and toggle to that apn. Let it pickup the 4G lte icon or whatever it is. Got to phone app settings advanced settings and make sure you don't get an error. Then switch back to the Nextgen apn.
Worked for me.

For Christmas I got an iPhone 5s for my daughter,to replace her iPhone 4s.Its been so long since I've used an iphone. Christmas morning she opened it.I told her just swap your Sim card,she came back down kinda upset and said it didnt fit.Now I felt bad,ATT isn't open nothing I could do.I remembered once I took a Sim that was too small and crazy glued it to a iPhone 3g Sim tray and it worked.So I googled cutting an iPhone 5s Sim card,and there's actually a template you can DL and trace where to cut.For some reason my printer didn't want to work so used a ruler and the dimensions that were on the site,it was micro Sim to nano sim. I got really sharp heavy duty scissors and cut it,sanded the sides and corner,even the non contact side because the nano is like a hair thinner,fit right in sim tray and worked perfect.I've offered to give her my S5,nope lol these kids and there Iphones.And that phones IMEI was on my plan that day,it was an ATT phone from someone who recently got a 6plus that I got it from.

Question Using an eSim without a physical Sim on AT&T

Hi, I'm trying to use an eSim only (without inserting a physical sim) on my pixel 6 pro on AT&T, however I cannot get it to work. When I say not get it to work, I mean with eSim only there is no cell signal and no data signal. Physical sim works fine on both signal and cellular service. If there's another Us AT&T pixel 6 pro user who's using only the eSIM for service please respond and let me know whether or not eSim only works for you. Thanks.

Not an AT&T user here, am using a European carrier, just from anecdotal perspective: I also use eSim only and never had an issue on my P6 Pro. So it appears to be something carrier related.
I remember that I had to activate my eSim, maybe you also have to do this? Did you try out the eSim/your contract before using this phone?

Yes, I tried 3 times with the help of AT&T and we couldn't get it to work. I'm going to return the device for a new replacement to see if that fixes this issue. Thanks for replying.

Before going through the hassle of returning the device for a potential fault - do you have a family member or friend, whose simcard/esim you could try out? That way you can find out if your phone truly has a defect or if its your contract/the specific esim. Of course you can always let them replace your device, but that will take a couple days, maybe there are faster ways to narrow the problem down.

i tried again today at another AT&T corp store and walked out of the store with it working as expected (wait till the end). the person helping did additional research on my issue and discovered the P6P shipped to me "was not activated" with the inserted physical sim (which i removed when i received the device). apparently, AT&T will park (or associate) a new device with a specific number when shipping to you vs. walking in to buy a device on an existing line. nonetheless, i'm going to return the phone because the data connection isn't working consistently; data is on and then after i go to website, data turns off. i'm probably going to send it back to AT&T next week.

Finally got the phone working, but will get an unlocked version later; this one is still going back to ATT.

I'm using an ESIM on AT&t and even originally got the phone My plan was to have a physical TracFone SIM card and my AT&t esim which is exactly what I had on my Pixel 5 and it worked great. Both SIM cards work great... when the other ones not active or inserted. It is impossible to use with both SIM cards like I did on my Pixel 5. Constant signal loss and the majority of the time. No signal at all. But as soon as I deactivate or remove a SIM card it starts working perfect.

I had a problem with provisioning eSim on my TMobile, well technically its sprint still, says tmobile esim but I am on sprint billing. Anyways, you need to maybe try to do it on another WiFi access point or something. I had issues with mine activating over Viasat2 satellite internet. I live in that area, its either LTE or satellite for internet. Had to tether to my work verizon phone to activate it on sprint/tmobile lol. If the connectivity to the esim server is not great, you'll split hairs until it is.

Exactly the same issue/behavior I had with my AT&T P6P on the AT&T network so I returned mine today. I'm contemplating a Fi version to see if it works for my use case.
