Give me a good reason to put the new SIM card in

Is there any reason to put the new SIM card that came with my phone in? I put in the same one that I've been using for years (Dash->G1->G2->SGS2) and it works fine. 4G shows at the top of the screen. I haven't tried a speed test yet, but I'd bet I get 4G speeds the same way I did on my G2.
So, what good reason is there?

Right now, there is no reason. When the wifi calling becomes available it will require the new Sim.

do you have some sort of sentimental connection to that sim? why not just use the new one to make sure yoour up to date?

Where did you guys find the new sim card? Is it in the plastic wrapper with the manual/user guide? I don't see it in the box and I haven't opened up the plastic wrapping the manual/user guide is wrapped in. Fyi I did buy my phone from a T-Mobile.

I replaced my five yr old sim card with it because my old one seemingly caused some bad 3g data issues. I found this out by swapping sim cards with a friend who just signed with T-Mobile and an SGS2. I replaced my old one with the one that came with the SGS2 and now I'm not only seeing improved 3g speeds but also better call reception.

Quick question, my sim is about 3 months old. Will it work with wifi calling when it is released or is the SIM in the box even more "updated" than a 3 month old sim?

No, the GS2 and Amaze 4G are the first phones to shop with the new sim cards.

Are you sure about this? where Did you get this information? sounds a bit unrealistic that ota. Uupdates are tied to the sim in the box.

They aren't. They are tied to IMEI's. Two things you really need it for; 1. If you want to use WiFi calling after the maintenance update in a couple weeks, you will absolutely have to have this SIM card. No questions. It will not work. 2. After time, the older SIM cards will fail. This could lead to data access, call drop, sms sending/receiving and signal issues. If you have one now to activate, saves you a call and a trip to the local store for a replacement.

In the tmobile system we have 2 classifications of Sims. 2g (your dash) and 3g (hspa+).. make your conclusions

Actually the new Sim is a completely new revision designed for the high speed 4g network. It also has the gold contacts in a different design which is part of it look at old and new Sims if you don't believe me. I forgot the name of the new Sim but its what was taught and explained for tmobile techs (tier 2 and up support). Also most stores do not have this Sim revision in yet so use the one supplied in your box. 90% of most tmobile employees have no idea about the new Sim and only guess when asked.

Your dash? The dash also later came in a 3g version. Also hspa+ is our 4g version and hspa is 3g.

How do you come to that conclusion.. the size and shape of the gold has changed multiple times over the last few years so your point is invalid.. TECHNICALLY the only difference with new Sims for our device and amaze is for the new WIFI calling network. As of Nov 12 wifi calling will not work on our phones with older sim cards
Sent from my SGH-T989

Yes but those were different revisions and also had a different contact design. Please I am not arguing with you but I am correct on this matter.

I don't know what idiot told you that is all it was designed for and I doubt that was sent from us at corporate. What's your name T-Mobile associate? You can pm me and I will look it up tommorrow to show you what you should have learned correctly. Also per tmobile policy which you signed when hired you need to remove the tmobile associate title on your xda account credentials if you are a tmobile employee.

***T-Mobile GAB Sim Card***

So ive been doing researches cuz i would like to get my "WIFI Calling" to work...
So i called T-mobile to see they had a solution for me...
And this is what they said:
They told me that the Normal Sim Card i have is not supported to use WIFI Calling.....
So the guy said that i need to buy a "GAB SIM CARD" that supports WIFI Calling and its price is $20
I even Google it to see how they look but didn't find it...
What do you guys think?
Should i buy it or is there another way to do it without buying this SIM CARD
Sent from my SGH-T989 using xda premium

I had to get a new one for it to work as well.

That's bull****, they should have updated your SIM card when you bought the phone off of them unless of course you didn't buy it from them

sim cards are and should be free from t-mobile. go to your local store.
BUT, when you got your phone (if you bought it from t-mobile) it should have come with a sim card, that supports wifi calling. That's what I had to do, had them activate the sim that came with my galaxy s2, and then started using it instead. and bam wifi calling

It sounds like you went to a dealer.
Not every t-mobile store is operated by t-mobile. Many of them are dealer stores that charge whatever they want.
Dealer stores are usually pre pay only, but there are some authorized to collect commission off contracts and that have access to t-mobiles "quickview" account software. (Quickview is the system the infamous SOC codes are set up in.)
A lot of dealers incorporate sleazy practices and do not conform to the standards set by t-mobile. They do things like charge egregious amounts of money on SIM cards, and may not honor the return polices set by t-mobile. They also sell lots of "out of production" phones they get at good deals ex. Lg-g2x for under 240 dollars wholesale and resell for over 550.
Call t-mobile and ask for a corporate store, not a dealer store.
T-mobile seems to allows this since "money is money"
As for the SIM card I don't think it has anything more than you're IMSI and your half of the encryption cypher, (for establishing a network connection) and some limited memory regarding contacts and previous network connection frequencies . . . The fact that your SIM card did not support wifi calling is most likely because t-mobile identified it a a card not to allow access to for whatever reason. I don't believe there is a technical deficiency in you're old SIM preventing such a technology, or support in you're new one for that matter.
But then again, I am no expert. If anyone knows more please share.

Why would you pay for it? They are free

Because TMobile likes to get every dime they can. Usually they are free in the corporate owned stores.....franchises have the option to charge

Initially they told me $20 too...but I explained to them in a very gruff voice that I give them over $200 a month and I am completely done with my contract and would be happy to switch carriers. Manager came out and gave me the SIM. Since that day I always go to that store and the Manager normally sweetens my purchase with a discount on what I buy.

T-Mobile is actually using new type of SIM cards - GBA cards that allow WiFi calling via the SIM, and the device must support it as well - you must have a GBA SIM and a compatible device for this type of WiFi calling to work.
If I remember correctly, only the Galaxy S2 and the HTC Amaze support WiFi Calling through the SIM, rest of the devices have it using the app.

Incredible 2 Verizon phone on walmart straight Talk

I have been doing some digging and I am fed up with big red. I was wondering if I can use my Verizon incredible 2 on straight Talk. From what I understand is they use at&tt and Verizon towers for service. The phone has a sim card in it, so what would stop me from just swapping out sim cards or is there a way to make my sim card work? I have my phone fully rooted with ics on it now. Anyone have any thoughts on this?

Unfortunately there is no fast way. PUKs are unique by SIM card. Only your service provider will know the PUK specefic to your SIM card. In addition, do not guess the PUK 3-5 wrong guesses will completely lock the SIM and then you'll need to order a replacement SIM card.

[Q] Can ISIS be used with an AT&T SIM card on this phone?

I know the T-mobile version of GN3 is powerful and almost fully compatible with AT&T. However, I still have one question: after the phone is unlocked, can ISIS be used with an AT&T SIM card on this phone? Have any of you tried?
Thanks!

Nobody tried?

Someone tried with a VZW note 3 without any success using T-Mobile service... figure the same would be true with an AT&T version.

I had tmobile and isis was working. Switched to att with correct sim and won't activate. Called numerous times but they can't get it to work

It is a no go
Is just got a AT&T ISIS Sim but couldn't activate on an unlocked Tmobile Note 3. The funny thing is that nobody on at&t support could help me because none of the support people (who just can read from scripts btw, their response was to call Google since the ISIS wallet is downloaded from the google store) even knew what ISIS was... So I am giving up and going back to my Nexus 5 and google wallet... Shame on you AT&T and Samsung...

Same here. Can't set up account with att isis sim on unlocked tmobile phone. Anyone else have any luck? or alternate way to set up account? on the brighter side, I seem to be getting slightly better signal with the new sim..not sure if its just a coincidence
