IPhone sales break records, now which carrier plan is best?

Just three days after the launch, Apple sold more than 10 million iPhone 6 and iPhone 6 Plus models, setting a record. Tim Cook thanked all Apple customers for making it the company's best launch ever, saying this weekend's sales shattered all previous sell-through records by a large margin.

"It means Apple is stronger than ever. The larger iPhones could sway consumers back from Samsung," said Mike Prospero, reviews editors at Laptop Mag.

Besides deciding on a phone, choosing between a carrier plan is just as important.

T-Mobile's Simple Choice may appeal to the business traveler due to the number of perks it offers, including free international data roaming, as well as free music streaming. Prospero said it will cost around $2,300 over two years.

If speed is an issue, T-Mobile is good for those who live in Los Angeles, but Verizon is the speediest in most cases, according to Prospero.

Each carrier has different perks. AT&T's Next plan allows consumers to pay the full price of the iPhone in installments, has trade-in prices for existing iPhones and offers a $100 credit on a consumer's bill for adding a new line to their plan.

Sprint's Simply Unlimited Plan is unlimited text, talk and data for $50 per month. But there's a catch. "Sprint's plans tend to be the least expensive, but its LTE network is the smallest of all the carriers, so you won't get nearly as fast speeds as you would on the others," Prospero said.

The iPhone 6 and 6 Plus will be available in more than 20 additional countries on Friday, and in 115 countries by the end of the year.
