J1 SIMs Opiniões 

I have contacted customer service through email 2 times today and both times I have received an thorough and helpful answer and solution within a few minutes. Thank you.

With a Huawei Mate 10 Pro it worked excellent, I had reception at places where others did not.
I was really happy during the last 3 months!

In my opinion the reception depends on your phone too, not only the SIM card.

Finished my 1 year internship in Detroit and service worked great. WiFi was not always available and their mobile data were very dependable.

I've never been so disappointed my 2nd time calling and still didn't get any help, they didn't recognize my details but money is pulled from my account for this Sim something has to be done about the customer care line it's supposed to be helpful.

worked for my internship this year and the one time i needed service it was within couple of hours. I agree with comments that unlimited service is best!!

mobile phone worked fine for 5 month intership in New York. The 2GB runs out fast so i recommned unlimited if no cable in yoru apartment.

Worst ever support. Plus the service doesn’t even work. I tried calling t-Mobile to fix the issue and they said I’m not the authorized user. You can’t even reach them. Is this Scam?? Because I paid over $100 dollars for this plan.

good price and worked as advertised. I used their unlimited plan services for my 6-months J1 stay.

Got monthly service just recently with a cut off the week after I signed up. Customer support are slow at responding and when they do, its normally a totally different person so you end up having to explain the whole situation again. Trying to explain how an email chain works to them would be like pulling teeth, they're that bad

Worst support ever. One month in advance I wrote e-mail to update my plan to unlimited data (wrote 3 emails) and I have got no response. After month they cut my again they basic rate.

Worst provider ever.

The worst provider ever! I extended my phone plan every month and they blocked my number two times without no reason. I stuck on the traffic in the middle of the day with no signal! Then they helped me to solve my problem and it happened the today day too! Also, they have the most unresponsible customer support I've ever seen. They didn't response me few hours.
Terrible experience. Never again! I'm so disappointed, this service should help J1 interns but with j1 sims, it's even worse. I'm so upset. Still without signal using wifi in the town.

Can’t contact J1simcards sim tried emailing them no with reply. Daughter is unable to use the unlimited international calls that she has paid for.

Trustworthy - competent and good service.

I have been using J1sim for almost 2 years, never had an issue with.
The network is fine, not the best one but with unlimited talk worldwide, you can't complaint.
