iPhone 7 and iPhone 7 Plus go on pre-order in the 28 countries

As promised, the Apple iPhone 7 and iPhone 7 Plus went on pre-order today. The phones are available in 28 countries through the company's official website, while carriers are rushing to announce their pre-order deals.

SIM free:

Let's start with the iPhone 7 and iPhone 7 Plus SIM-free pricing. Here is how the pricing in the US, UK and Germany (which matches most of mainland Europe) compares.

Mind you, shipping times vary and a specific color and storage combination might result in weeks of waiting. It will probably only get worse as the day progresses so you might want to act quickly.

US Carriers:

In the US, the iPhone 7 duo will be on offer by all four major carriers - AT&T, Verizon, Sprint and T-Mobile. Here's what each of them has to offer you.

AT&T

AT&T will let you have the 32GB iPhone 7 for 24 monthly installments of $27 on its Installment plan or its Next program. The 7 Plus starts at $32/month.

Verizon

Verizon's installments plan costs the same - $27/month for the iPhone 7 and $32/month for the 7 Plus. However, with the Big Red you also get the option to get the phones with a single upfront payment on a two-year contract - that would be $199 for the base iPhone 7 and $319 for the 32GB iPhone 7 Plus.

T-Mobile

T-Mobile has an interesting trade-in offer if you have Apple iPhone 6, Apple iPhone 6 Plus, Apple iPhone 6s or Apple iPhone 6s Plus. The "uncarrier" allows you trade in your phone and get $650 in monthly bill credits for a 2-year period.

Alternatively, you could get the T-Mobile ONE plan for $70/month and have the iPhone 7 (32GB) for additional $27.09/month for 2 years.

Sprint

Similarly to T-Mobile, Sprint offers a trade-in an iPhone 6 or newer, or a Samsung Galaxy S7 and a Samsung Galaxy S7 edge (in working condition) and get a free 32GB iPhone 7.

Other than that the pricing matches that of Verizon - $199 one time payment or $27.04/month in 24 installments.

UK Carriers

Vodafone

Vodafone offers the 32GB iPhone 7 with a variety of plans. The entry level plan costs £28/month for two years with an upfront payment of £400. The high-end VodaFone 30GB Red Value Bundle is priced at £58/month an an upfront payment of £30.

The iPhone 7 Plus (32GB) is also offered with the same plans. Prices for the entry-level Standard plan are £32/month with an initial payment of £400. The high-end plan is £63/month and £50 upfront payment.

O2

O2 offers the iPhone 7 (32GB) with 5GB of data with unlimited text and minutes for £59.99 upfront payment and a monthly installment of £50/month for 2 years.

The carrier's ultimate plan gives you 50GB of data with your new iPhone 7 (32GB) for £59.99 upfront and £80/month.
