Does sprint have the imei problem

I've been ignoring it all this time cause I was on stock and I thought imei were a GSM version of esn and sprint phones didn't have them
Can someone tell me the effect of having no imei on a sprint phone and how it happens
Thx

sprint and cdma phones don't use imei numbers. so no there is no imei bug

That's what I thought but if you go to settings>about device>status we have an imei number
But thanks for telling me it don't matter
Now I can go on a flashing spree with no concerns

Sprint does have IMEI numbers but they don't use them like the evo lte, you might loose it but you won't problems connecting to the network a verizon guy loss his but still connected to network lte like normal

If you lose your IMEI you will probably not be able to connect to LTE. 3G and everything else should work, but I'm pretty sure LTE will not.
I say this because LTE is a GSM technology, which is why I think we have IMEI on our phones in the first place. I haven't heard of anyone that reported the bug yet on Sprint, though.

Help?

I have an unlocked Gt-i9505 and all frequencies match for higher network signals but all I'm getting is edge. My Imei number I think is wrong. And I could really use a detailed description of the engineering mode.
Sent from my GT-I9505 using xda app-developers app

So you're trying to use the i9505 on T-Mobile in the USA? If so, I think you will only get 3G/4G speeds if you're in an area where the 1900Mhz band has been refarmed.

I have an unlocked Gt-i9505 it's through t-mobile originally but my service provider is straight talk. I have compared the frequencies for the network in my area along with my phone I funny understand why I'm only getting Edge. I should at least get 3g. It may have something to do with my Imei number, it says I have an s3.... I don't have a bootloader and there isn't an option to pick my network mode like 3g/4g/edge /lte... Messing with engineering mode I made my wifi icon blue for the first time ever but it didn't stay.

You might have a AT&T Sim card through Straight Talk. Are you sure you have a T-Mobile compatible Sim card?

Honestly I have no clue. When I purchased it from the website they didn't offer a choice let alone sizes. I had to trim the sim to be a micro. How could I tell?

My phone is stuck on E

I bought my phone on craigslist I restored it and all that. 4G was working till about a month later it started to be stuck on E. I called Tmobile they took me through the steps on how to fix it, but it didn't work. I updated my phone to 4.1.2 and it went to 4G Lte and then after an hour it went back to E. Does anyone know how to fix this???

It shows LTE/4G/3G/2G 4G/3G/2G 2Gonly
I checked LTE/4G/3G/2G. And it still gives me E

Are you sure that the phone wasnt dropped? It could be the attenna being messed up
Sent from my SGH-T889 using xda app-developers app

I noticed on mine that when I have lte checked it often would to edge and dont recover but when on 4g/3g/2g it keeps steady 4g. I think im in area with poor lte coverage.

Yes I'm sure it was not dropped

Well your phone aint blacklisted that for sure. Try this http://forum.xda-developers.com/showthread.php?t=1846488

I'll bet it was bro good luck tho
Sent from my SGH-T889 using xda app-developers app

From what I gather from the thread, I don't think that your phone is blacklisted.
Who is your service provider? T-mobile.
Enter *#06#.
The IMEI will be displayed.
The link below allows you to verify whether or not your imei is valid on the T-mobile network.

From what you find, you can do a few things. Please post your results.

I'm assuming that your phone model is the SGH-T889 T-mobile Samsung Galaxy Note 2.
So, you need address why you are getting Edge Only. I bet that the NV Build is corrupt OR you
need to reflash your modem.
Here is how to proceed if your NV Build is corrupt.
On December 28, 2012, Darkshado[w] posted a full NV backup for the T889, IMEI removed, at the following thread: http://50.23.216.69/showthread.php?t=2068041&page=2
Using "NV-items reader_writer v1.0," write to the device with the corrected IMEI using the file from Darkshado[w] as a template (replacing the memory block decimal address 550 with your hex equivalent IMEI). If the NV Build is corrupt, this approach should resolve this issue.
Otherwise, I would try to reflash the modem, which modem is dependent of course on your STOCK ROM version that you currently have installed.

Go to dialer and hit *#2263# it will allow you to choose from gsm wcdma and lte if you like your hspa use the wcdma and go to all or 1900

Sim card not recognized

I just attempted the unlock and root. But when im inserting the sim, it says no sim card when there is one. Ive inserted it correctly. Changed the mobile network settings to gsm only.
It will not read any sim. , lyca mobile, T-Mobile. Will not even read the iccid number in setting.
Update it reads sprints SIM but not my T-Mobile...
