Earlier this month, it was discovered that Lycamobile quietly made changes to one of its prepaid plans. Instead of offering 4GB of high-speed data under the $29 Unlimited International plan, the T-MobileMVNO increased the data to 5GB. But it looks like Lycamobile is not yet done with the increase. Customers who wish to purchase at least 3 months of service under this plan can enjoy more data. Instead of getting 5GB of data, customers can enjoy 6GB of data monthly. The plan also comes with unlimited domestic and international talk and text. Again, the 6GB of high-speed data offer under the $29 Unlimited International plan is only available to those who buy at least 3 months of service in advance. The offer is also available to new and existing customers for a limited time period.
