SpeedTalk Mobile $6 Preloaded Smart Watch SIM Card Kit for 4G LTE Kids Senior Smartwatches & Wearables | GPS Tracking | 3 in 1 Simcard - Standard, Micro, Nano | No Contract | 30 Days Service Plan

Bought this along with a kid's smart watch. Was able to get it activated and test it in the smart watch in about 15 minutes. You do need a credit card to activate but it is not charged. (It says $0.00 fee). I checked my bank and it has a $1.00 and another $-1.00 transactions (so the net is zero). It's probably because they want to make sure it is an adult that activates the card.Tested calling from and to the card with the new phone number given and it works. So, it works as advertised. Make sure you save the documentation and also the big card that contains the SIM number, you may need it in the future.(Yes, some of you are not comfortable with the credit card thing. I understand.)Update 01: I finally download the mobile app that is used for manage the account. It appears that it's on auto -fill - in a way it is a good thing, and explain why they asked for a CC during activation. Going to need to wait until the end of the month to find out. The app is a little "clunky" but its functional. So far, the experience is good.

Using this with a kids smartwatch, the instructions are not very good. Giving the watch to my daughter for a birthday gift, I activated the SIM card after some difficulty and calling customer service to get the correct website, and the watch was working; calls and messages were going through just fine. On the day of the party and giving the watch to her, now it has no service. Have made several phone calls to get this resolved, they have been of no help. Don’t waste your money like I did.

Easy activation. APN setup is a bit tricky. Affordable

I got this for my 9 yr old kids smart watch. I got it activated and everything and it doesn't work. I don't know if it's not compatible for their watches are what. I wouldn't recommend this.

I can't really say this is a bad product. I have no idea how it works but it was what was recommended for the watch I bought my child. apparently the watch was a waste of money and no sim card actually works with it.

I like it

I bought this for my son's smartwatch after experiencing nothing but frustration with another brand of SIM card. Despite others' reviews, I found it very easy to activate and install, and it started working immediately. Thank you!

Could not get to connect to watch! Kept showing messages were being sent on the app but never coming through. Verified compatibility with watch. Paid for card and service and never could use
