J1 SIMs Avaliações 

Used to be really good but then they changed service providers all of the sudden (this totally went wrong).
I got a new SIM card but wanted to keep my old number, this didn’t work. My new data is not working and everything is getting complicated. Should have just sticked with TMobile. Now it’s just a mess.

Everything was fine until I got an email from them saying that they're switching from T-mobile to AT&T all of a sudden. My service stopped and I was left without any signal or data for a couple days as I had to wait for a new SIM card. Got my new SIM card, requested same day activation. Nothing. Waited one more day, nothing. I emailed customer service multiple times as I was anxious to have my phone working again and they just told me they'll get back to me once they have an update. It's been like 2+ weeks and I still haven't heard anything back from them. In the end I just bought a new SIM card from my local T-mobile store because I needed a working phone.

The phone number I had under J1SIMS was the number that was tied to all of my accounts, apps, and resume. It was very annoying that I had no choice but to change my number and being left without any service for a whole week was inconvenient to say the LEAST.

If you're an international student like me, my suggestion to you is just go to your closest mobile services store and get a SIM card there. That's what I should've done from the very beginning. I didn't give 1 star since I had been using J1SIMS for the past 3 years without much issues.... until now.

At least customer service replies on the same day!

Absolutely worthless service. Had to transfer from T-Mobile to AT&T and the process totally got messed up. I ended up having to get a new phone number.

ZERO STARS.
I put 1 star because I couldn't do less.
Paying 50$ per month I couldn't have important call records for legal matters because they don't track calls. I was forced to change sim card and almost lost my number.
Don't waste your money with them

Cannot recommend at all. Canceled my plan midway through because of “changes with the carrier.” I was not informed about this and left without a working phone. Customer support did nothing to offer to fix the problem. Also the same day activation did not work. Overall awful experience.

Worst prepaid sim card ever, don't use that !!! I activated my one month plan before coming to the United states.
No network signal. Even if restart my phone and followed all instruction on their website.... I never received a network signal since i was here. I recommend to never activate this sim card and to choose another carrier its better trust me. 👍

Obviously very busy, too busy to get their service levels correct. Let me tell you a story of a company that promotes it is there for people and then fails. Before my trip to USA I contacted J1 SIM Cards and order a SIM 3 months before the trip. It arrived, I registered it and paid for it for the date my trip started.... All Good. Then I received an email a fortnight before travelling to say the SIM was canceled and they had refunded my money, but sent a new SIM. It will be there before you travel. Of course, it did not arrive. They, therefore, have left me without a service for the trip! Great. One job and they were unable to complete it.

No signal all the time, really bad service. Even they stopped my service for more than one week.

Reliable service and very helpful and responsive throughout the pandemic.

Very much recommend. I received SIM through J-1 program and compared prices. Offer was good and they say money back if not happy. Worked fine off plane in NYC and then again in california. Got stuck in usa and was able to extend service online. very helpful.

Not recommended. Did not work at all in new York ☹️ and in Montana ☹️ and in boston. Totally waste of money

I just completed 4 months of service with J1. They even extended service 3 days at no charge because my flight was march 5 and service ended the 2nd. They did this fast for me and there was never any problem with service in detroit. My colleagues who stay continue to use. I disagree with customer below. Only I select the months when activating and can cancel whenever so cambodia customer is confused.

First let me star of me giving 0 star, I am an exchange student from Cambodia I have Been in the United state for 8 months. I have been being from j1sim for eight month now which I did not give them permission to take out automatic payment from my bank account. I also haven’t have there service for 7 months they are charge for a service that I am not getting. Customer service is no help at all. They didn’t even try to take the matter in hand and solve the problem they just keep passing on the problem back to me. This is the worst phone company I ever have work with. I do not recommend there service. This is a scam. They are taking advantage of innocent international student. Be aware!!!!!!

Good:
- Solid 4G coverage (unless in rural areas but this is no different with any other provider)
- fairly well priced for unlimited data.

Bad:
- international phone calls cost extra but apparently have to be conducted through a separate app
- I get spam phone calls from the state my number is registered to around 4 times a day (which is a lot over a year)

Really helped me during my stay. Would recommend to a friend. Great service!

My card never worked, I've paid 50 dollars for a monthly unlimited plan. Even T-Mobile employees weren't able to activate it, telephone number I was given, didn't exist in their database either. Reimbursement doesn't exist in their dictionary.

the best of the best!!!

The best best service company Ive ever had in US like student, unlimited options for good price! I had service everywhere, I’ve never had any issues with J1 card. This is my third year with u guys and I’m really really happy u provide something like this. And also the best is, they provide me extra few days after my program finished, for free !! Thank you so much!

Possibly the worst phone company I have ever experienced in terms of service during my time on both coasts of America. It was absolutely terrible and in this day and age not having any service is a safety issue. The poor coverage wasnt limited to rural areas with many urban areas lacking in coverage also. I would advise people strongly not to buy.

Thank you so much, guys, for this great service from your side!)
It was pretty easy for me!)
Good luck!
