Keepgo is a wireless data company - they provide you with a SIM card that you can use in almost all countries around the world. They offer a pay-as-you-go plan where you pay upfront to buy data (1GB or 3GB at a time). I've been using them since mid-2016, and have been fairly pleased with their service. We bought the SIM card and wireless hotspot device, and the hotspit device came pre-configured, so we just turn it on and connect to the WiFi AP on our phones when we want data. The device itself supports up to 10 connections at a time, but we've only tested with up to 2.
So how does this work? Keepgo also offers a referral code that gives the referrer (me) 300MB of data, and any new customers 10% off their purchase. So if you're looking to get 10% off, and feel like helping me out, please visit my Keepgo referral page to get your 10% discount. Thanks!
