Great potential but not there yet

This system has a great deal of potential, and when it works it's excellent. That said, here are the downsides I've seen:

1) Occasionally, especially when moving from country to country, you need to delete the app, and all the profiles associated with service, and manually switch to your home SIM in order to re-establish connectivity with your home SIM, or even WIFI. This has happened to me a few times. You must delete the profiles otherwise you might connect to Home Network or WIFI but data will not work.
2) Voice quality is usually poor and in the top end passable but never excellent.
3) You cannot tether or use personal hot spot functions, meaning you can't take advantage of the service as a modem for your tablet or notebook. I can understand that they want to limit data usage but should at least allow this through direct tether.
4) As others have mentioned this is not a service for non-technical people. It has challenged me (mobile data professional) and I would consider myself an advanced user. So, if you are not tech savvy give this one a miss for now.

The savings you get from using the service are excellent. When it works, it works well. I am eager to see a more polished solution. If the kinks are ironed out I'd definitely consider using it on a permanent basis.

SMS & text message

The app could have a way for us to receive SMS and text messages inside the app for the phone number we’ve got. I don’t think this Sim Card service is valuable, just full of charges, expensive service and no messaging services. Once you are out of your region, you can’t get service or receive messages, then why pay for it? I am very disappointed and I wish all my money could be reimbursed, because this app is just propaganda.

Dual sim iPhone? No fun

I use 2 sims in my iPhone. Every other travel sim or local sim from other countries work fine but not this one. It makes the iPhone network cut out all the time, slow connection on main sim when the KnowRoaming profile is installed,... and so many other little things make this too much of a hassle. No thanks
