So I've been reading on these forums that some roms don't have gsm working. Can someone explain what gsm is and what it does? Sorry for noob question.

gsm = signal
without it there is no calls or texts
Or in other words, no calls or texting.
Ok thanks guys.

"Global System for Mobile Communications"
This technology uses a small SIM card to contain the mobile phone details such as your phone number & etc. This allows one to swap the SIM card into another phone and have it simply work. The SIM card can also store a limited number of phone numbers. The technology is used everywhere in the world, but only on AT&T and T-Mobile in America.

Not sure to understand since I'm not in those carrier and I can swap my SIM card into any other phone and it will still work. I'm in Canada and this works for any carrier for all I know. The SIM also contains phone numbers and can hold a bunch of SMS.

I forgot about the SMS storage. Your SIM card can be put into any other GSM phone. It could not be put into a Verizon phone, for example.

SIM card Slot can be used overseas!
I spoke to Sprint International services , they mentioned that I could use a local carrier SIM for voice and data as long as I used a 128 k sim card , also and obviously they dont guarantee quality of service of the local carrier !
Will update next week , when I hopefully will use a local SIM overseas...
128 k sim card. interesting.
yes, please keep us updated, i would like to know how it goes.

Hi, id like to know if the Photon 4G is CDMA or GSM with a Sim Card Slot? because im about to buy one from amazon and id like to know if it is one or both and how to recognize which one is it
It is both, it uses the sim for GSM and uses CDMA without the sim. You cant use a domestic sim for GSM, for now atleast.

Meaning you can't take a sim card from AT&T or another GSM provider within the US and plug it into Photon and expect it to work. Its locked out for GSM in the US. It works internationally though.
The 4g is Wimax !!!

LOL I totally had that typed out ready to post before I reread and saw that he meant the phone and not specifically the 4g. Unless I just misinterpreted that completely lol, which would make it the second time

I have just bought an unlocked Sprint unit from ebay, hoping to use the GSM slot for my primary pre-paid line in Nigeria, and the CDMA slot for one of the CDMA providers in Nigeria as well. I plan to take the unit to be programmed into a CDMA network in Nigeria; that will cost me about US$50. Meanwhile, I successfully rooted and flashed ParanoidROM JB, but I saw that it showed no GSM signal at all with the JB ROM, so I restored the original GB 2.3.5 Nandroid backup. There seems to be very little documentation on how the dual system works. Will I be able to use both the CDMA and GSM together, in a dual-standby fashion, in Nigeria?
I flashed the KDDI radio and cm10 and have used my MoPho on T-Mobile.
Don't forget to thank all who help!

Big Red won't activate it unless they sold it.
Hello,
I have a few phone numbers and am planning on setting up Straight Talk for my main # but would also like to use Tmobile for my vanity #. Does anyone know the APN / other settings in order to set this up on Tmobile? I just picked up a Tmo sim card and paid for the $30 plan.
Also, is there a way to get 3G/4G service? I understand w/Tmo that the AT&T Note will only be able to access the 2G service (bummer). Are there any other issues in setting this up to run both TMO and Straight Talk? Do I have to change APN or other settings each time I swap my sim cards?
Thank you for your help
first thing is your phone unlock? If it is you don't need to enter the apn, all you have to to is put your sim in the phone will recognize the right apn.

It should you might have to get a sim card that's international and a good Rom that works well with gsm networks if I'm not mistaking most other country's are gsm

isnt global mode in settings for going other places then the usa? doesnt global mode auto pick service after buying a sim card for czech republic cell services? im sure you can buy a prepaid service.
Depending on frequencies used then yes all the above should work in gsm based countries. At a minimum you'll have voice SMS and evdo data.

save yourself some trouble and call verizon BEFORE you go. They'll need to flip a (free) switch on your account to allow roaming on GSM networks.

That isn't necessary. And will give you a crap ton of roaming charges. International roaming ain't cheap.
Just pop a sim in from the Czech Republic and you'll be good to go.

Ok, so I dont have to do anything other than remove the verizon sim and place a local sim card? Will my Verizon sim still be active once I put back in or does it go dead for not being active that long? Do I need to rom my phone with GSM rom to do this?
Hi guys,
Just to let you know, I'm from Portugal and have the HTC DNA. Fully operational both stock and custom firmware. Everything works fine except LTE. Just need to create a new APN setting for the new SIM card.

Depends if you want to roam and keep your number when travelling abroad. I prefer to do it that way. My point is, if you plan on sticking with roaming on your Verizon sim, you need to have them enable gsm roaming on your account (cdma roaming works fine, where avaialable). I learned the hard way.

Ok cool guys, thanks, so do any of you know of a good carrier in Czech? I will be in Ostrava (Northeast part of the Country) I just need data for skype and gps.
Since our Sprint Note III have sim slot, will it be able to activate under different carriers that uses SIM card?
No, unfortunately the sim card is only used for international use and not for the actual phone number on the account.

From what I've read, the SIM card is also used for 4GLte. If you check another thread http://forum.xda-developers.com/showpost.php?p=46574528&postcount=8 one of the members found that his SIM card # didn't match what Sprint had so his 4GLte didn't work. Once they updated the number to match, 4GLte was restored to his phone.
