They sold a carrier locked phone to me, originally sold in US by a American carrier. (Still network locked when I inserted other simcards).
Indeed I was testing this Z fold3 on wifi for a month, working fine.
After a month I found this phone was originally sold by an American mobility carrier in USA.
They bought this carrier locked phone and sold it to me by describing 'Unlocked', which make me not able to use it on any Canadian sim card.
I have been asking them for a week but so slow to fix this issue. Eventually, they wanted me to ship it back to you for any further actions, which I don't agree with it for another several weeks waiting and possible non-refund situation.
For this reason, I give them one star who didn't check the phone mobile network status properly giving a customer wrong information and huge difficulties on using a phone.

The phone has been great but not perfect. The biggest issue is the peeling of the folded screen protector, though it's not as bad as the flip3. The shell of the phone seems pretty fragile, the phone has minor little chips from sliding out of my pocket in the car and falling between the seats. This is easily prevented with a case but that's my 3rd issue with the phone, case selection. Unlike most standard the folds unique design has limited the case styles making it harder to find a case with all the features you may need. Also the cases seem to be way more expensive than other phones. Lastly compatibility with gaming pads may lead to issues, though never tried myself.

For the positives, the phone is definitely impressive. It's fast, clear has a great size screen when opened and if you watch alot of shows on your phone while not minding the smaller screen, you can partially fold the phone to use it as it's own stand. I love this feature as I like playing something to fall asleep to and now I don't need the tv on that's so bright it wakes the wife. The camera is really good but not on par with the s22 ultra.

Overall great phone, I don't see myself going back to a non fold phone, again though it isn't perfect.

Recommend to everyone except those wanting the best phone cameras, really abusive on their devices, and possibly gamers who want to connect a controller.

I initially "upgraded" my Fold 2 to a Flip 3 - I was curious about the clamshell flip style and I figured that, since I hardly ever unfolded the screen, I wasn't really losing much.

I was losing much. I hadn't counted on the difference that the larger battery, faster processor, more ram - and the OPTION to unfold into a larger screen, rather than the other way around - all made to the experience. Woof! Consider me educated. I opted to grab this because specs-wise it seems pretty similar to the Fold 4 and a lot more affordable, and I love it. I'd heard horror stories about the Fold 3's battery life, and while it's too early to tell (I'm still in the can't-put-it-down honeymoon phase), it doesn't seem to be much different from the Flip 3, so I'm okay with it.

The stylus support is a little niche, but you'd be surprised how much easier it is to literally write a long wall of text rather than use a phone keyboard. And, lucky me, the seller that I purchased my model from included (as extras) not only a case, but also TWO styli - handy, since I bought a Fold 3 for my wife as well. Good looking out, Brandon.

All in all, if you're: 1) curious about folding phones, 2) wanting something on the newer side, and 3) not NEEDING the latest and greatest with your entire being, you'll make out pretty well with the Fold 3. Maybe just make sure you have a couple of wireless chargers sitting around the house, though, just in case.

I was soooo super excited to have this unique phone--until I peeled the clear screen protector off of it (because it began to bubble--especially in the fold of the phone).

What Samsung DOESN'T tell you is that if you pull that plastic screen off the phone (when opened) your entire wide screen will go wonky and then eventually out.

This phone cost wayyyyyyyyyyyyyyyyyyyyy too much to not have a warning sticker regarding that flaw.

The ONLY redeeming thing about losing use of the wide open screen is that (once the phone is closed) there is a front side of the phone. It is very thing in width but you can still scroll/use your phone for the Internet, cell phone etc. as normal.

The OTHER messed up part about it is that Samsung would not exchange it (even for a refurb one) but kept offering me "discounts" on applying for another phone ( Samsung Fold 4).

Needless to say, I won't be buying this phone again (or upgrading).

Let me also add, I only got a few months usage of enjoying that beautiful, unique wide screen before it went wonky.

Not happy...
