Testimonials

We Make Our Customers Happy

"Easy to Navigate and Use"

My experience on STiprepaid.com was great! I really liked the fact that I can add time to my customer’s phone and his father who lives in Mexico. STiprepaid.com was so easy to navigate and use. The instructions were very clear, and the terms and conditions were short and to the point. I'm glad I was able to save my information for future use. I felt it was secure to use my debit card because of the security features and the commissions are better than other services. I will definitely keep using this service in the future to add funds to my customers’ cell phones."

"Great Service and Commission"

I like the way this service simplifies the purchase of airtime to cell phones in Mexico, the page is well designed, I mean, It didn't take me more than 3 minutes to sign-up to be a seller. There is nothing to dislike. I would definitely use it in the future; most of my customers are Mexican and have their services with Iusacell. And StiPrepaid.com offers a great service and commission structure. Thank you!

"Simple Solution"

STiprepaid.com seems like a simple solution to add minutes to customer’s cell phones. It's easy, convenient and the site is pretty easy to navigate. The thing I like the most about STiprepaid.com is that it is quick and easy to add money to a cell phone. My employees can process many transactions in minutes. And the high commissions are not too shabby. Thank you!

"These Are Very Exciting Times"

We invested a lot of time in designing a product for our retailers that would be so simple and fast to use, that basically would not need any training to start using. But still provide a modern and fully functional portal. Allowing our customers to focus on what they like to do which is sell to their customers. These are very exiting times, where we see the STi brand come stronger than ever.
