I can't seem to test my phone and the card I ordered months earlier without buying a PEN. I don't think this should be necessary. And the only support seems to be by email, which is a pretty poor way to handle support.
Company Response
Hi Andrew,
Thank you for your review and your feedback. We take great pride in our Customer Support and we are very surprised that you had a negative experience. We can see that you reached out to our customer support team regarding a possible duplicate order and they assured you that a duplicate order was not placed. We take certain preventative measures to protect our customers from credit card fraud and to prevent mistakes like duplicate orders from processing. We are sorry that these measures caused an inconvenience for you.
We are happy to work with you to get your SIM card working. Please reach out to us via Support Ticket, Phone or Chat; all of these methods are available to all of our customers.
We hope all your travels are safe and enjoyable!

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
