I was a Koodo customer before. Then I switched to WIND. Now I'm back again. In most respects, I'm happier with my service here, but I do notice I miss a few services that WIND has. One of those is a text message alert if you missed a call while your phone was off/out of service (which, with WIND, happened constantly). While my service is great, my phone isn't always on, and it would be nice to know if someone tried to call me without hoping they've left a voicemail. Rogers offers this too, though I'm not sure about other carriers. It'd be nice if Koodo had it.
