I was going to start a new thread about T-Mobile's Pay by the Day plan, but found this thread, so I'll resurrect it. I too have some questions about this plan, but my situation is different from the OP's. I'm in the U.S. and have a Lumia 920 on AT&T as my main phone. I've just ordered an unbranded, unlocked Lumia 620 to use mainly as a mp3 player/media device on WiFi. I've been thinking that it would be good for it to also have the ability to access data and make phone calls, should I ever need it (maybe on days when I just want to slip a small phone in my pocket and don't want to carry around my 920). The T-Mobile Pay by the Day plan seems to be a good fit for my needs, since I would only very occasionally need data/phone service on my 620. What do you guys think? Would it be the most economical option? I was also considering the $30/mo plan T-Mobile offers at WalMart, but I don't think I'd use it enough to justify spending $30 every month. If I get the $3/day plan, $30 would equate to 10 days of service, and at this point, I don't think I would use that many days each month. I assume when I'm home with access to WiFi, the phone won't use any data. And just to be sure, I don't accidentally access data services (i.e. apps with background tasks), I figure I can just disable data services on the phone's settings. And then only enable data when I need it.
So, aside from figuring out if the Pay by the Day plan is the best option for my needs, my other questions about the plan are:
1. What's the minimum amount I have to add to my account?
2. After I load my account, how long is that money valid for? A month? 90 days? In other words, how frequently do I have to add money to the account?
3. Like the previous poster, I too would like to know if the 200 MB of data is a daily limit. In other words, each day that I access data services, my limit is 200 MB. From their wording, I think that's what they mean.
4. Any other fine print I should know about?
Would really love to hear from anyone who uses or has used this plan. Thanks!
