A tweet from T-Mobile (TMUS - Get Report) CEO John Legere Tuesday morning told followers the company's iPhone orders were up roughly four-fold from the previous year. 

While sales figures were not released, the company said Apple's (AAPL - Get Report) new smartphone set the record for most orders in a single day. Sprint (S - Get Report) also said orders are up roughly 375%.

Do these reports matters? They do when you break the numbers down, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Mad Dash" segment about Apple, the AAP holding. 

Last year, T-Mobile had 23.6 million pre-paid customers. Now it has 30.9 million. That's significant because it shows that even without a four-fold increase in subscribers the company is seeing a massive boost to iPhone orders. 

Cramer speculated that if T-Mobile and Sprint are seeing this strong of demand, Verizon (VZ - Get Report) and AT&T (T - Get Report) are likely seeing strong demand as well. 

Apple opted not to share its opening weekend sales figures with the public this year, but the positive reports from cellular companies has got the stock moving higher, up 2.5% on the day, despite the notable decline in the broader market. 

It also helps that the company is releasing its new iOS 10 update on Tuesday as well, Cramer said. The company betting against Apple, may very well be proven wrong, he concluded.

At the time of publication, Cramer's Action Alerts PLUS had a position in AAPL.
