Really really like IQ Mobile for both the customer service and product. The reason for 4 stars, which might be a little unfair, is due to a change in policy whereby the 100GB for use in Europe for 90 days is now only available once in a rolling year whereas previously if you used it in the UK the 90 days would start again. As someone who travels to Europe for at least 180 days a year this product doesn't work. They have said if we buy sims for other devices they'd increase the term, this feels a little unfair. So when our contract ends we'll look elsewhere but keep an eye on IQ mobile in case things change.
