s4 wont read simple mobile sim card - T-Mobile Samsung Galaxy S 4

Im trying to get my simple mobile sim card to work on the T-mobile galaxy s4, i bought the phone straight out of wal-mart. The phone says no sim insert sim card. help would be much appreciated

Make sure you push it all the way in and also make sure your sim card is activated, is not defective, and it might be that the phone isn't for tmobiles network? It sounds dumb but some phones when they're not part of their carrier it says that.. And that's all I kno...

Simple Mobile is supposed to be on T-Mobile's network.

How long have you had your phone? I just got mine 3 days ago and a quick read through the manual said Verizon will unlock the SIM after 60 days of use. They at least want something out of having a customer purchase a world phone from them.

How to tell if handset is sim free or not?

Hi
Just bought a Note II, I was told it was a sim free model, and whilst its accepted my tesco sim card without issue when I log into google play on my pc its brought it up as an O2 Samsung GT-N7100 so the question is have I been sold a O2 handset thats been unlocked? I know it doesnt really matter that much but curious more than anything
Or is it possible tgey have flashed it with a o2 firmware my mistake?

You could try. Borrowing a friends sim and see if you can send a message. If yes, the you are likely sim unlocked.

The N7100 is the international version so it should be sim free.
To test your if your phone is unlocked, insert another sim card other than your "tesco". And if it shows enter sim unlock code, it is locked, otherwise it is unlocked.

Tesco runs on the O2 network. That is why, sometimes Tesco handsets will work with O2 Sim Cards only etc...
Yeah I know, hence why im looking to change o2 data coverage is shocking and I cant use sky go or tvcatchup using 3g as it comes up with some rubbish about saying im abroad...

Have unlock code from AT&T, how do I unlock without having non AT&T sim card?

I got my unlock code directly from AT&T. I do not have another carrier sim card to place in the phone (that will fit, this is a smaller than standard size sim card). There are people in my office that have T-mobile, sprint, or Virgin but have full size sim cards.
Any suggestions or instructions??
Thanks!!
I've heard about a few people going into t mobile and asking to borrow one. They shouldnt mind they are probably thinking you'll use on tmob after unlocking

I'm wondering - would a SIM from an AT&T MVNO (such as RedPocket) be considered a "non AT&T SIM card" for purposes of unlocking?
I just bought an "H20 Wireless" micro sim card on Ebay for .99.
Hopefully it will do the trick...will post an update (if anyone cares) if it does or doesn't work when I receive it.
Why don't you just store the code and use it when you get any non att sim? I mean, why waste money, even a $, unless well you have a willing non att friend who can lend you his sim.

Because I just got a Galaxy S 4 and I'm selling the phone. You wouldn't spend a $1???
Gotta spend money to make money sometimes haha

Got it. I didn't think of selling phone. I was thinking on my lines given that I am a frequent traveler, and get code from AT&T within 90 days or earlier of getting a new phone.
OK. so i put the H2O sim card in and reboted several times and all I get is "sim card not provisioned".
So I just borrowed a Verizon sim card from someone in the office that has a Verizon Galaxy S III and got the same thing.
I am not being prompted for an unlock code?
What Am I doing wrong???

Hacked:Sim Cards!

Just found out that someone finally discovered a way to hack Sim card's. Don't know about you guys but I'm a bit concerned. They say that 5 million phones could be affected. What does you guys think?

The article I read said it was only a certain type of older sim that was vulnerable, and even then the hack didn't work 100% of the time. If you have an older sim and you're worried, go to a Tmo store and tell them you need a new sim. Then you should be fine. If you got your sim recently, you're already good.
Trust me, SIM cards are next to impossible to hack. I have my s3 and I want to use both phones (obviously one will be off while using the other) use the s3 at work so not to break my beloved s4. Use s4 at home and when out. Got a SIM card reader and spent days figuring out how to clove it. Second you touch the SIM card, to figure out it's ki, boom SIM card is locked and destroyed. As was said before only the older ones are able to be touched.

Network Availability

Hi
i have just purchased one of these bad boys in the 4g flavour but my carrier is 3 mobile so data is blocked as my sim is a phone sim and not a data sim
so anyone in UK can you please tell me what network you are on where you get full data calls and text
Much appreciated
Thanks
Lee
Hi Lee. Isn't it just a regular sim? Is it on contract or payg?

I am on three mobile one plan.....I am looking for a payg sim that I can put in my note 8 amd get calls text and data.....I can get calls and text but data is too important to forego

You can put in the phone Sim card with no problems. If you need to manually enter the apn, it's three.co.uk.
Sent from my GT-I9505G using Tapatalk
APN is already set to three.co.uk
I also have a letter H+ with data arrows flashing up and down
Not a huge response to my query, all I am asking is anyone using a note 8.0 as a phone.
I can go with watever network allows phone sim to work in a tablet but it will cost me a top up to find out who will work
Thanks for your help

If it's unlocked, then all sim cards should work. I've used it with a 3 sim and also a virgin mobile sim.
