HTC One box

1.p.m ET: retail launch on Verizon, online launch on AT&T, Sprint; available in the U.K. from 4 p.m. GMT

The all-new HTC One (M8) has been officially announced, and we're now able to bring you details of retail and online availability for the device in the U.S., Canada, and U.K. As previously announced, the new HTC One will go on sale at select Carphone Warehouse locations in London from 4 p.m. GMT. In the U.S. the device will go on sale in Verizon retail stores at 1 p.m. ET, and at that time it'll also be available online from AT&T and Sprint. Meanwhile T-Mobile will launch the M8 in April. In Canada, Rogers, Bell, and TELUS are also kicking off pre-sales today with in-store availability later on.

You can buy HTC's new flagship on launch day on both sides of the Atlantic.

On-contract prices with a two-year plan will vary between $199 and $249 depending on the carrier, HTC tells us — we'll bring you carrier-specific announcements as soon as details are made available. The company says all four major U.S. carriers will be selling the M8 at retail by April 11. (Which also just happens to be the global launch day for the Galaxy S5.)

If you're buying off-contract, the new HTC One will set you back $649, and that's also the price of the Unlocked and Developer editions, which will be made available directly from HTC's website. In addition, there'll be a Google Play edition HTC One (M8) available to pre-order from today. The Google Play Edition will take 2 - 3 weeks to ship and costs $699, available here (only in the U.S. for now).

We'll add specific carrier information to this post as we get it.

  • Sprint (US) — Sprint will be selling the M8 for no money down and 24 monthly payments of $27.09. Otherwise, it's $199.99 down on contract once it hits stores in early April. You could go "All In" for $110/month or settle with 1 GB for $70/month.

  • T-Mobile (US) — T-Mobile will be offering the M8 on April 11 sans contract for $0-down, and $26.50/month over two years. T-Mobile plans start at $50.

  • AT&T (US) — AT&T's M8 is available here. You'll be shelling out $199 on contract, and plans start at $65/month.

  • Verizon (US) — Verizon has finagled exclusive availability until April 10, so they're where you need to go if you just can't wait to pick one up. In-store availability kicks off tomorrow, March 26. The real sell here is Verizon's BOGO deal; buy one, get the second for free, so long as both are activated on a two-year term. Verizon is having a Google Hangout event at 3 PM ET today if you want to get in on that. Verizon also notes that the M8 is Isis-friendly for contactless payments. Get your hands on it over here for $199 with plans starting at $60/month.

  • EE (UK) — The 4G-centric network will have the M8 on sale online and via telesales tomorrow, March 26, and in stores on March 27. Customers buying on a £37.99/pm "Extra" plan (£29.99 upfront cost) before April 10 will receive twice the amount of data of EE’s standard 4G plans — taking their monthly limit up to 4GB — for the duration of their contract. To sweeten the deal, EE is also offering customers who buy online between March 28 and April 10 free return flights to one of 12 European destinations.

  • Carphone Warhouse (UK) — Apparently Carphone Warehouse has been having events at their stores for the M8 launch, though you can check out the offer online here. You'll be looking at £549.95 SIM-free or £42/month for no up-front cost.

  • Three (UK) — You can buy the M8 from Three UK today, but you can't snag it for pay-as-you-go just yet. No gold version, but the other colors are in stock. Expect to pay £459.99 up-front, or £49 up-front and at least £38/month.

  • Vodafone (UK) — Vodafone UK is getting their stock of M8s in store on March 27th. It'll cost £42 for zero-down. Vodafone is also tossing in a free HTC BoomBass speaker for the first 3000 shoppers. A handful of stores in London will have them in stock tomorrow, if you're really antsy. Get shopping online over here.

  • O2 (UK) — O2 has the M8 available now for £49.99 up-front and a £38 monthly plan, or £609.99 with no strings attached. Order (online over here)[https://www.o2.co.uk/shop/phones/htc/one-m8-metal-grey/].

  • Phones4u (UK) —Phones4u is offering the M8 in the UK and tossing in $25 Google Play credit, a case, and a BoomBass speaker as a bonus. You can get it for free here for 24 months on a £42.00/month plan.

  • Unlocked-Mobiles (UK) — If you're looking to go SIM-free and unlocked, Unlocked-Mobiles will have it on March 28 for £534.98.

  • TELUS (Canada) — TELUS is offering a nice little accessory bundle worth $120 with their M8. It includes a double dip case, HTC Fetch keychain fob, and a juicy 9000 mAh battery bank. You'll be able to snag one for $229 on a two-year plan, or $700 outright from this page at 1 PM ET. It looks like TELUS is the only one with the silver model in Canada, if that's a deal-breaker. Plans start at $80/month. Prepaid subsidiary Koodo will also be offering the M8. Their data plans start at $34/month.

  • Bell (Canada) — Bell's M8 is available for sale right now online! Like TELUS, it's $229 on contract, and Bell's plans start at $80/month.

  • Rogers (Canada) — Rogers will have the HTC M8 in stores on April 10 for the same $229 as the other carriers. You can lock down your order through the Rogers Reservation system.
