I have a cricket sim card (in an adapter - nano >standard) in an Incredible 2.
The phone is unlocked.
When I put the sim card in, in both global and GSM mode, I get an error of an invalid sim and it won't let me edit the GSM settings or apn.
Has anyone done this? I just need a phone for the time being. I'm using the sim card in a different phone to type and post this, so I know the sim card is good and active.
Any ideas help? Phone is stock 2.3.4
Thank you in advance.
How exactly did you get the phone unlocked?
called Verizon, got the code. put it in, phone restarts, then says its unlocked.
Any help with the sim issue?

Alright, sounds like it should be gsm unlocked. Are you sure the cricket sim is GSM? I thought cricket was cdma but I might be wrong. If you can, try a tmo or att sim in the phone and see if you get signal. Also next time can you quote me so I can see your reply? Thanks.

Cricket is owned by ATT, I think they phased out CDMA in 2014 or 2015. They use all ATT towers now.

Ahh, im behind on this kind of thing. Does the sim work on any other gsm phone? I would also try to flash a stock ruu.

Using the sim in a different phone to write this post. Phones are bone stock.
thank you for the continued troubleshooting, really would like to get this figured out. I've been around here much longer than this username. Normally I find the answers without the need for more specific help. This one has me stumped though.

Just try to RUU to stock and factory reset. Sometimes you need to wipe everything after entering the code so the phone will autodownload the apn settings.

So I mainly use my phone for texting and that's usually over WiFi but last week I noticed that I wasn't getting any reception and I clicked in settings and noticed that the Cellular Service was set to CDMA instead of GSM. I clicked on GSM but it said that there was no SIM card inserted and switched back to CDMA. I checked the back to make sure that the SIM card was there and it was. I took the SIM card and checked it with someone else's phone and it worked perfectly but when I used their SIM card, my phone still would not switch to GSM.
Does anyone know if there is any fix to this? I'm pretty good about not dropping my phones and definitely have not dropped this phone so I'm not sure what may cause the SIM read to malfunction. Going to go to the Verizon store this weekend to get it checked but the problem is, I'm not with Verizon so I might not get a cheap fix for it. Any suggestions would be great! Thanks!
EDIT:
Mr.Highway, thank you for putting it in the right place. I'm new to this whole thing.
To anyone else: do you think getting a voltage meter and checking to see if the SIM card area gets electricity would help?
EDIT:
Called HTC and Verizon and they won't fix it because I'm with a different carrier. And I don't fully trust myself in switching out the SIM card reader...help?

It started to not get signal in CM7 so I reflashed CM7 but that did no good. I then unrooted the phone and returned it back to stock, was still no good.
Miss read.
Hmmmm odd if you wanted a cheap repair you could try repairuniverse.com I think. Just Google the part and its for sale somewhere
Thread moved to Q&A
If I helped, give thanks, if you please.
........Death before dishonor........
Anyone have suggestions?
Im new to this phone
So the original carrier is Claro PR. I have succesfully unlocked the phone cause im using AT&T SIM on it and it has signal and all but it wont make/recieve calls, nor text and wont go on the internet.
Anyone have had this happen before on unlocked phone? I was thinking on rootinh it and throwing a AT&T rom to see if it fixes it but im asking first before trying anything that can brick it
Did you unlock it using the free method or by a code?
For data, did you check the APN settings? Under network preferences, did you select auto? Are you sure the SIM is registered on the network?

I'm at a loss as to why it doesn't work even though it gets a signal. Maybe something is screwed up in the service menu settings.

OK, so this weekend I decided to try my AT&T SIM Card with my Note 4 from Sprint. I thought it would ask me for a SIM unlock code or something but it recognized the card and showed "3G". However, I got the card icon which said "Invalid SIM Card".
Any idea why I did not get the prompt to input unlock code? Thanks!

The sim inside the sprint note 4 is only to access the LTE network. So since you took the sprint sim out, you would be only receiving 3g. That is why you are receiving the invalid sim card error, because its not using it.

So I am getting that error because the SIM card is not using LTE? I don't get it. If the phone is unlocked, shouldn't it ask for an unlock code?

There's been plenty of discussion in this forum about bringing SM-N910P to other networks. I'm no expert, haven't done it myself but what I read repeatedly posted is that radios in this version did not allow LTE on domestic carriers when unlocked. Seems a common issue with phones made for CDMA carriers; taking them to another carrier may not meet your expectations. If the limitations are acceptable, maybe you consider going ahead and weigh your options.
Again, there's plenty of threads in this forum discussing this but here's one that I found that may help. To me, it's been rare for @idone to post these days but he posted here.

Thanks for the reply. Yeah I am aware that the Sprint Note 4 would give me 3G or H+ but not LTE which is fine by me. I was wondering why the phone did not ask me for the Unlock code to begin with when I threw a GSM card in there.

Did you find your answer? Or still asking?
It's likely Sprint will give you a MSL number but not unlock the phone to use on domestic carriers. I think you still need to unlock it for that purpose. But the developer I referred you to can do this with or without the MSL. His tools are capable; his service is a full unlock for domestic. I don't think you need the unlock for carriers outside the U.S. the way the phone is currently. Sprint may clear a phone for domestic carrier use but not unlock it or help you activate it. You'll likely find no carrier to help you unlock it either.
I'm sure there are ways to do it yourself but it's gotten more complex with Lollipop and Marshmallow. I'm just not sure how it's done because I haven't fully done it. Only walked through it partially back in KitKat but kept Sprint SIM and service. Didn't try another SIM card.

No I'm still looking for an answer. I have messaged idone on their website and sent a PM. I need this unlocked and take it to H2O. Sprint gave me the MSL code to be given to a GSM carrier but I call BS on that. Strange thing is the damn phone recognizes the AT&T SIM card as a 3G card all right but still says "Invalid SIM Card".

No expert here, but dont you need an AT&T SIM card that has your phone unique ID info programmed into it so it registers on AT&Ts network?
I thought the MSL would just unlock an area in the phone where you would change DNS type info to AT&T's towers/network.
Hello, I'm wondering if anyone has tried this. Obviously, the bootloader would need to be unlocked.
It works but doesn't. You'll still be locked to Sprint and the T-Mobile ROM will see that and you won't get service until you unlock the SIM. Other than that, it seemed okay when I tested it. Only tried it for a quick 15 minute boot though... Tested my flat mate's T-Mobile sim and my Sprint sim. Both wouldn't work.
Actually, I forgot to mention that Sprint has already SIM unlocked my phone. Knowing that, I could in theory at least flash the T-Mobile firmware and then with a TMobile sim get Tmobile wifi calling and VoLTE? Also would the phone then automatically get Tmobile software updates?

I wouldn't know. It's worth a try. You won't brick your phone. If it doesn't work, the switch back to Sprint firmware is just another flash all away.

I may do so. The only risk is that I'd have to open up a new T Mobile account to fully test, and then I'd be scrambling (and out of pocket) if I couldn't get the tmobile flashed sprint phone to work. Do you have a link for the T Mobile and Sprint firmware?

I'd just ask one of the employees at the store if they'd let you see if your phone would work. I'm sure one wouldn't mind throwing their SIM in to make a sale.

Just bought an unlocked SM-G960U1 from Samsung.com. I used my active SIM card from the old Moto G4 on the S9 and it didn't work. Checked IMEI with Verizon and it said the phone should work perfectly with their network. I talked to tech service by phone and they told me to look for LTE/CDMA in Settings but I only have LTE/3G/2G and such. in settings. What is wrong with the phone? Is it a real unlocked one or they shipped me a wrong model? Please help. Thanks.
Reset the APN settings
then reboot the phone
and make sure you have store bought sim, they do update SIM models and sometimes it can matter.

Thanks for answering. I reset all APNs to default and reboot but it didn't work. It seems the phone does have any setting related to CDMA network.
That phone is perfect for Tmobile and Metro PCS ...
Is Verizon using GSM type phones ?

Yep there is definitely something wrong. Maybe I missed it but I don't see where you mentioned getting a new sim. The best option would be going into a Verizon store and getting them to put in a new sim. If that isn't possible get them to send you a new sim.

Thanks for the reply. I am using my existing sim card which was purchased two years ago. I will visit a Verizon shop and see if a new sim can do the trick.
New sim card is the solution
Thanks all. A new sim card from Verizon activated the CDMA connection of the new G960U1. I am a happy S9 user now.

Does your model number change to SM-G960U, after activation with a Verizon SIM or does your ABOUT PHONE section list your S9 as an SM-G960U1?
