Sprint Denies Widespread Issues with Slow iPhone Data Speeds

Since the iPhone 4S debuted on Sprint on Friday, a number of the carrier's customers have been complaining of slow data speeds. While the issues are not universal for iPhone users on Sprint, they do seem to be affecting a substantial number of customers.

PCMag.com now reports that Sprint has issued a statement on the issue, characterizing the complaints as a "small number of reports" that the carrier is looking into.

"As always, Sprint is carefully monitoring the performance of the 3G network. We are looking into a small number of reports of slow data speeds when using the iPhone 4S, however there are also reports showing that Sprint’s network is the fastest, such as the Gizmodo report that came out earlier today. Speed tests represent a moment in time and are subject to many variables including weather, time of day, device, and proximity to a tower. Sprint will continue to monitor the feedback we are getting from our customers and will investigate and resolve any issues that may arise," the company said in a statement.

As the report notes, it is unclear exactly what Gizmodo report Sprint is referring to as supporting its case, as the site's informal speed test survey is indeed showing dramatically slower average data speeds for Sprint compared to AT&T and Verizon.

PCMag.com also notes that Sprint has already been measured to have the slowest real-world 3G network speeds of the three iPhone carriers in the United States, and thus the iPhone itself may not be having a significant effect on the carrier's network. And with some customers perhaps being new to Sprint with the iPhone, they may have been unaware of the carrier's network speeds.

Guys, give them a chance. I am personally giving them a chance until my 14 days are about to run out. I used Sprint before and they were excellent, unless something changed, they should get over it.

BTW, remember it is mostly those with horrible speeds that come to MR or Sprint community to post, happy customers are unlikely to post.

I'd rather have a sub-par internet performance for unlimited monthly than to have blazing fast internet that's only good for 2GB.
That pretty much sums up my feelings as well.

Insanely fast speeds are no good if you have a data cap.
Uh you realize that sub-par means you won't ever reach 2gb anyway... Not a great argument you made there.

My Sprint was slow as balls on Friday when I received it, but since Saturday it's been perfectly fine.

I was getting absolutely impressive 3G speeds last night. (100KB/s down 50KB/s up) On launch day, they were garbage.

I'm wondering if they fixed it and are denying anything was ever wrong in the first place?

How are those impressive? Those are horrible 3G speeds, unless that's the norm for Sprint.

I am with Sprint now and I hate it every time I saw the ad how they were great about the unlimited data plan and they said ATT and VZN charge you more after 2GB and TMobile slows you down after 2GB, yet they were the only fast and unlimited... In reality, they were slow from day 1 till the end....:(:(
