I have an S4. I am currently travelling and added on the travel plan. For the first couple of weeks, the data would turn on when I checked the box to turn it on (I leave the data roaming box checked as well). For the past week and a half, the phone will only connect to the basic network (for phone calls and text). There is an R above the bars, not the normal LTE that shows that data is connected. I'm in a fairly dangerous country by myself and I am quite displeased with the lack of customer service from koodo. Uber is the only safe form of transportation and I am only able to connect if I find WIFI, making me feel very unsafe.
