What's the difference and how do I know which one I have?

[beman39]

ya know what? I was just thinking that the other day and was gonna post the same question but forgot to do it! so peeps? who's got the answer? inquirer minds wanna know!

I think it has to do with how much storage the device has.

[MSFTisMIA]

Has to to with the cellular radios employed by the device, which matches the RM designation...RM-937, RM-938, RM-940. AKA another way to class carrier variants depending on the global region where the phone is shipped and sold.

The 1520.3 is the unicorn device, which mean it has North American LTE radios, including the AWS band for T-Mobile. If my memory is correct, that would make it the RM 938. The RM-940 is the AT&T exclusive and the RM-937 is the global offering.

RM-937 is the international 1520, but no LTE in the US. RM-938 is the Latin America 1520, it has the radios and lte signals for both T mobile and AT&T. . Both have 32gb of storage and wireless charging. RM-940 is the AT&T 1520, 16 -32gb but no wireless charging. It has been discovered that you can manually enable the 1700 mhz radio in a RM 940 and get flawless T mobile service.

What he said.

The 937 and 938 are also 32gb devices. The 940 ATT is 16gb with no qi wireless charging. The 937 will run LTE here in Canada for Rogers as they support 2600 band LTE.

I have the 937 and I'm happy with it. HSPA is fine for me.

[tboy2000]

So the 937 has wireless charging and has 4G for UK?

[Dr_8820]

Yes, it should.

Your RM-937 is the "Global" model. Most common in Europe, Middle East, parts of Asia...

[floppyedonkey]

The higher the number the better, 1520.3 = the best.

[tboy2000]

So is this correct...

RM-937 = 1520.1
RM-938 = 1520.2
RM-939 = 1520.3

?

Um no. I would argue the 937 offers more than the 940 if you don't care about lte.

RM-937 = 1520.1
RM-938 = 1520.2
RM-939 = 1520.3

Sort of. Should be:

RM-937 = 1520.1 Global 32GB
RM-940 = 1520.2 ATT 16GB
RM-938 = 1520.3 Global with USA LTE and AWS 32GB

And the RM-939 (No LTE for those parts of APAC that have TD-LTE and can't use the FD-LTE radio in other 1520 models) should = 1520.4

The RM would indicate planning/design order and the 1520.x progression actual release. That's my guess.

Hi there Officially there is no 1520.4

[RumoredNow]

Hi there isn't a 4th.

There are 4 variants of the 1520.

1. RM-937 "Global"
2. RM-938 "Americas"
3. RM-939 "China"
4. RM-940 "US/AT&T"

Go to Settings -> extra+info, then scroll all the way down at bottom, it shows you what Model & Type you have.

Some one mentioned it has to do with release. I believe that is the determining factor for the 1520.X place holder. You can check all the software Labels for each of the four variants and will see the below. I don't own all four just know what the label under Extras+Info reads. Maybe this will help clear this up.

1520 (1520.0 I suppose) = (seems to be China Unicom frequency and bands only)
1520.1 = RM-937 = (Unlocked European variant with Frequency and bands for that region)
1520.2 = RM-940 = US AT&T branded (frequency bands and provisioned Cellular settings determined and at the mercy of that carrier)
1520.3 = RM-938 (Unlocked North American variant, most versatile for US users)
