In an ideal world, a phone's SIM card would work with whichever carrier you choose. No having to sell a Verizon HTC One to switch to an identical one on Sprint. A device with a carrier-free SIM card could go wherever its owner wanted it to. The only problem is, such a product is currently illegal across most of the planet. Only in the Netherlands is the story starting to change.
Pre-paid smartphone users were in an uproar a few months ago when Straight Talk stopped selling AT&T SIM cards to new customers. At the time, all we were able to ascertain was that the cards were sold out online, but a few retailers like Walmart still had some in stock. Well, they're back – in a limited sort of way.
When you go through the sign up process, the website will only show you T-Mobile or AT&T cards for a given ZIP code.
Almost all the GSM phones released in North America have a single SIM card, but there are a lot of areas of the world where having a dual-SIM device is a big advantage. These devices can utilize two networks at the same time for calls, data, and SMS. For when two just isn't enough, LG is going to soon offer phones with three SIM slots.
LG is teaming up with MediTek to create the new triple-SIM devices, which will almost certainly never arrive in the US.
We've been hearing for the past few days that users have been unable to get new AT&T-compatible SIM cards from Straight Talk and Net10 websites. The only option seems to be the T-Mobile SIM. This was causing quite a bit of consternation as the Nexus 4 is finally starting to ship again. The complete absence of AT&T SIMs from both sites led many to wonder if AT&T service was no longer being sold by these Tracfon-owned entities.
