How to Find a Compatible Unlocked Phone


I’ve been noticing a lot of posts in the community, and other forums, about folks that purchase phones that they believe are compatible with Republic, but it turns out they aren’t. In most cases, it is because the manufacturer makes multiple versions of the same phone, but only one of those versions is compatible with Republic.

Moto Z & Z Play

Here, we have the case of the manufacturer reusing the model number of a phone of multiple versions of the phone. This model XT1635-02 is used for the North America Unlocked Version, the Brazilian version and the International Dual SIM version of the Moto Z Play. It also appears that 1650-03 is used for the International and North American Unlocked versions of the Moto Z. Of these, ONLY the North America Unlocked version will work with Republic. There are some things you can check to verify if it is the North America Unlocked version: First, does the SKU include “NARTL”? If so, it is the compatible version. Also, on the phone itself, does the phone have dual SIMs? Then it won’t work. Finally, if you have the phone, you can check the Settings – About Phone – System Version and look for "en.US" there for the correct version.

Samsung Galaxy S7 / S7 Edge

The unlocked versions of the Galaxy S7 and S7 Edge are easier to find. Their model numbers (SM-G930U and SM-G935U) are only applicable to the unlocked versions. That being said, there are a number of unscrupulous sellers on eBay and Amazon selling phones that are NOT the “U” version of the phone, but labeling them as such. These sellers are buying carrier branded phones, reflashing them, and selling them as the “U” version. While these models may or may not activate with Republic, they have incompatibilities that will limit your coverage and provide an inferior user experience. There is generally one way to tell that the phone you’re looking at is one of these “frankenphones”. In the listing, does the seller mention that the phone will only work with GSM carriers? Or that it doesn’t work with Sprint or Verizon? If that’s the case, you should skip that phone, as it isn’t the factory unlocked version.

Samsung Galaxy S6

It is quite honestly nearly impossible to get a compatible S6 used. When Samsung released the unlocked Galaxy S6, they used the same model number (SM-G920T) as the T-Mobile version of the phone. However, the T-Mobile version, won’t work with Republic. In addition, Samsung sold very few unlocked versions of these phones, so nearly every SM-G920T that you’ll find used, won’t work with Republic. The only way to tell if the phone you’re looking at will work with Republic is to check the actual Android build of the phone or to verify the SKU, instead of the Model. The compatible SKU is SM-G920TZKAXAR and you can find the supported builds In the Compatible Phones document. (Samsung is still selling the compatible S6 new here:

Samsung Galaxy S8 / S8+ / Note 8 / S9 / S9+

Here, we have an issue with Samsung creating a new, and confusing model number scheme. Depending whether you are looking on the phone itself, or you’re looking at the box, or the longer SKU listed on websites, you’re looking for two different things.
On the phone: The model number listed MUST be SM-G950U1, SM-G955U1, SM-N950U1, SM-G960U1 or SM-G965U1. The “1” is very important. Unlike previous Samsung phones, the plain “U” version is NOT factory unlocked, and therefore NOT compatible with Republic.
On the box or websites: In this case the SKU must start with SMG950U, SMG955U, SMN950U, SMG960U or SMG965U and MUST end with XAA. The letters in between don’t matter, as they simply indicate color and capacity. To add further confusion, it appears that some retailers are using an entirely different SKU when selling the unlocked version. I’ve confirmed that at least Best buy and ABT Electronics have placed a sticker on the boxes that they sell that shows “SMG950u1Z?AX”, “SMG955u1?AX”, “SMN950u1?AX”, “SMG960u1?AX”, and “SMG965u1?AX” as the SKUs for the US unlocked versions. Please note the “?” mark can be replaced with any letter as this letter indicates only color. These SKUs will work as they are the US Unlocked versions.

Nexus 6

Once again, we have a case of sellers selling phones with a model number that looks compatible (XT1103) and then saying that the phone doesn’t work with CDMA carriers. This either means that the phone is the international version, reflashed to look like the North America Unlocked version or that the phone is blacklisted with the CDMA carriers because of unpaid bills or something similar. In either case, the phones are to be avoided (and I would recommend, so is the seller). While the phone MAY activate with Republic, if issues arise, Republic will be unable to assist in working to improve the coverage or troubleshoot.

Google Pixel / Pixel XL

Recently, I’ve seen a number of listings on eBay for the Google Pixel and Pixel XL that advertise themselves as the Unlocked Verizon version of the phone. While the Verizon version of the Pixel is compatible with Republic (as Google doesn’t allow Verizon to modify the software on the phone), a number of these listings state “Will not activate with Sprint”. In these cases the phones are equivalent to the “frankenphones” I’ve described above in the S7 section. These phones may activate with Republic, and work on the GSM carrier partner, but in case of coverage issues will never be able to be activated with the the CDMA partner (Sprint). I would advise that these phones be avoided if you’re seeing service with Republic.

Moto X4

This one is fairly simple. Some retailers use the Model Number, XT1900-1. When they use this things are easy, because it matches the Republic documentation. Some other retailers are instead using the MPN (Manufacturer’s Part Number). In this case, they phone will be listed as PA8S0006US. These are the same phone, and no matter which way it is listed, it will work with Republic.

Moto G6

Republic now supports the Moto G6. Once again, we have the fun on multiple model numbers. The Motorola Model number is XT1925-6. In some cases you may see the phone advertised by its part number. In this case, the phone will be listed as PAAE0000US or PAAE0002US. These are the same phone and no matter which way it is listed, it will work with Republic.

I’ll update as more troublesome models appear.

Thanks for the reminder, added.

Will there ever be an an expansion of accepted model numbers for the Samsung S8+?

Updated 11/25/17 to add information regarding the Galaxy S8/S8+

Samsung Note 8 Model Compatibility

For the S8, does the SKU AND the model number both have to meet the requirements listed above? Or does one or the other work?


They should have both the SKU and Model number as those combos don’t change. If you notice something that doesn’t match, please let me know!


I’ve got another question, which I think is related, but please correct me if I’m wrong… does it matter if a phone is sold as “Verizon unlocked”? How can a phone be unlocked if it’s still tied to a carrier?


Phones can be carrier branded (and previously locked) but then carrier unlocked. That being said, no such phone works with Republic. All Republic compatible phones are “factory unlocked” which means no carrier branding.


Thanks for the response! I’m looking for a new phone and would like to try the whole BYOP program, but am struggling to find phones that match all the constraints. I’m unsure of whether or not this is the right place for this, but would you be able to check this link & let me know if it looks compatible?


The Z Play can be a challenge. XT1635-02 is the correct model and the description doesn’t say anything regarding dual SIMs, so it should be the correct version. The best thing would be to contact the seller and ask them to give you the information under Settings – About Phone – System and see if en.US is in the answer (in which case it is the correct version).


The purchase web operation for checking compatibility for the s9 phone says: Buying elsewhere? Follow these steps.

  1. We only support the North America unlocked version of this phone. Look for one of these model numbers in the product details: SM-G960UZKAXAA , SM-G960UZBAXAA , SM-G960UZPAXAA

Yet this post says it absolutely has to have a ‘1’ in the model number…What gives?


Two different things. The Model number on the phone itself reads “SM-G960U1”. The longer SKU on the box is as you’ve listed in your post. It is addressed above in my post:


I agree it’s confusing and not explained well. I recently recommended a clarification and was ignored. Samsung Galaxy s8+ Model Number



The post clearly states: “On the phone:” before the part indicating the “1” is necessary and that is absolutely correct, with no exception.

As of today, is this still up-to-date information? For instance, would a note 8 with MPN # SM-N950UZVASPR still be unsupported? Thanks!


Yes, the article is correct and no, the Sprint version (the model you indicated) won’t work with Republic.


Added Moto G6


Hi! This forum is super helpful because it’s so specific with phone models but I’m a bit confused about the Samsung Galaxy S8 phone requirements. Are the numbers on the box stated in the original post the only acceptable ones? (It’s been a few months). I would like to BYOP with the number on the phone as SM-G950U1. And the number on the Best Buy box as SMG950U1ZBAK. Will this work? I was wondering if Samsung has released a new batch of phones but RW hasn’t updated the list above… Much thanks in advance!


Can you please share a link to the listing as a search on the Best buy some isn’t coming up with anything showing that model number. Once I have the link I can verify compatibility and then update the article as necessary.
