Just checked their web site and now all U.S. customers can order online. I have an unlocked Lumia 620 that I use as a second phone. I'm currently trying it on T-Mobile, but the coverage in my area is horrible. Around my house, I either get Edge or "No Network Found". Needless to say, I'm done with T-Mobile. Now I'm debating whether to go with AT&T GoPhone or Aio Wireless. I also have a Lumia 520 ATT GoPhone (couldn't pass up the deal when Amazon had it for $88), but I haven't activated the sim yet. Just using it on WiFi. I believe the GoPhone sim would also work on my 620. I'm wondering if the Aio sim would work on the 520. I'm assuming the 520 is locked to AT&T. I've read comments in other online forums where people said their Aio sim worked on locked AT&T phones (even those still under contract), but I've also read comments that said the phone had to be unlocked for the Aio sim to work. So not sure which is true. Anybody know?
Since Aio and GoPhone both use the AT&T network, I assume coverage would be the same for both. My primary phone is a Lumia 920 on AT&T and the coverage here is very good and I get LTE. I know the 620 isn't LTE capable, but I assume I should get 4G HSPA+ here. If it's true that you can sign up for the $40 plan on Aio if you bring your own phone (on their web site, it says that plan is for basic phones only), then I'm leaning toward Aio. GoPhone also offers a $40 plan, but it's capped at 200 MB, compared to Aio's 250 MB. And with Aio, they just throttle the speed down after 250 MB, vs. GoPhone which would cut off data access (granted they do have the option to buy another 100 MB for $5).
What are everyone's thoughts on Aio vs. GoPhone? Pros/Cons for each?
