A pair of reports are out today from Opensignal detailing the state of 5G as well as the broader mobile experience in the US.

Blame it on Sprint

VoLTE will reportedly be required on T-Mobile starting in 2021

AT&T's 5G network is now available nationwide, making it the second major American carrier after T-Mobile to hit the milestone.

SoftBank plans to sell up to two-thirds of its stake in T-Mobile early next week, sources told CNBC's David Faber Tuesday.

SoftBank Group's stock was last 10.58% higher on Wednesday morning after skyrocketing more than 12% earlier in the session.

'The only natural option,' according to confidential 2015 report

T-Mobile's newest 5G network is just about ready for action.

The 5G race is heating up.

SoftBank, the owner of Sprint, is "open to all options" including an acquisition of rival T-Mobile USA, according to its chief executive, amid expectations that US president Donald Trump will be more receptive to megadeals.

T-Mobile CEO John Legere said iPhone 7 preorders hit record levels, totaling almost four times more that the prior record holder, the iPhone 6 in 2014.

HTC's flagship handset, the HTC 10, is apparently not selling well. T-Mobile has decided to dump the device after just two months on the market.

Sprint, the third-largest US wireless carrier, jumped 8.3% amid speculation that the company is getting closer to merging with rival T-Mobile US.

Apple's 4S topped the list at all major carriers offering the device in the US, while the Samsung Galaxy S2 took the crown at T-Mobile. The S2 also came in second at Sprint and AT&T, sandwiched in between Apple's 4S and iPhone 4, while the Motorola Droid Razr and HTC Rezound rounded out the top three at Verizon, where the S2 is not sold.

Nokia may be moving toward Windows Phone, but with the T-Mobile Astound (C7), it shows that with a few needed upgrades, Symbian can still function as a good entry-level smartphone.

Nokia is targeting those feature phone users who haven't yet made the move to a smartphone with the new Nokia Astound. It will be available April 6 through T-Mobile USA for $79.99 after rebate and with a two-year service agreement and qualifying voice and data plan.

AT&T has said it will buy T-Mobile USA from Deutsche Telekom AG in a cash-and-stock deal valued at $39 billion that would make it the largest cellphone company in the US. The deal would reduce the number of wireless carriers with national coverage from four to three, and is sure to face close regulatory scrutiny.

Samsung is a big beneficiary of Android's rise, selling more than 3 million Galaxy S phones, and capturing the mantle as leading Android handset provider in the U.S. by accounting for a third of all Android phones sold in the country.

The Comet measures 4.1 by 2.2 by 0.5 inches (HWD) and weighs just 3.6 ounces.

T-Mobile is careful not to attack the iPhone itself, suggesting that T-Mobile might not want to directly antagonize Apple in the event that it gets an iPhone deal of its own.

As T-Mobile loses its iPhone exclusivity in Germany to O2 and Vodafone, Apple has begun offering the iPhone 3GS and iPhone 4 unlocked without a contract to German customers, with the 16GB iPhone 4 model selling for 629 euros.

Sprint's CEO, Dan Hesse, got the rumor mill churning yesterday when he spoke to the Financial Times about another possible merger between his company and T-Mobile.

A day after Google confirmed its Android media event next week pricing details and the terms of sale were leaked for its highly anticipated Nexus One smartphone.

T-Mobile and Orange are to merge their UK businesses, creating a mobile phone giant with 28.4 million customers. The deal between Orange-owner France Telecom and Deutsche Telekom's T-Mobile UK will see a business with sales of 9.4bn euros (US$13.5 billion).

Mobile phone operator Vodafone has declined to comment on a report that it is considering buying T-Mobile UK.
