Ugh. Can't submit my online order for pick-up, keeps saying the card number is wrong. I'm watching the pick-up appointments dwindle away

Trust me when I say SMS/MMS is CSFB related. I bought the HTC One Max a week after launch, and could not send or receive texts on LTE at my home, granted it was Band 41 instead of 25. When I set it to 3G mode, texts went through fine. However now, texts go through fine over LTE at home because the CSFB issue was fixed. I posted this problem in an earlier thread and everyone came to the consensus it was CSFB related.

 

Exactly, setting the phone to CDMA only mode instantly fixes SMS and call issues. Will call in and let them know something's wrong.

The HTC One Max is a Sprint Spark (therefore tri-band) device that doesn't do simulaneous 1x/LTE... it's therefore a device that uses eCSFB, right?

If I'm right, then the problem belongs here... otherwise, please let me know where I should post it... thanks!

My One Max has really strange behavior when connected to LTE which leads me to believe that it's having ECSFB problems. The reason I'm saying this is because I have non-triband devices to test with which I can ensure are connected to the same tower under the same conditions.

In my room, I get LTE 1900 (UCF/DCF 1912.5/1992.5 says Signalcheck) at around ~-95dBm. The signal fluctuates if I move around the room, but the lowest I can get it to go is -105dBm (which is in my closet). Even then, I don't experience losing signal and the phone disconnecting from LTE.

However, when using this, I have several issues:

• SMS and MMS never come in and are never sent
• Ping fluctuates up to 6000ms
• Download speed slows to ~800kbps (very consistent) and once it drops, it doesn't improve until airplane mode is toggled (probably an unrelated issue?)
• Occasionally, downloads and uploads both stop. However, the phone still says it's connected to LTE, but I get a notification that says "Could not connect to mobile data connection." (or something similar.) During this time, I cannot receive calls, I cannot sent or receive messages, and cannot use data whatsoever. After 10-15 seconds, everything suddenly starts working again.

The reason I'm suspecting it's eCSFB is because a regular HTC One (M7) and a Galaxy S3 work flawlessly for hours without a single hiccup.

Thoughts?

I'm getting a very consistent 14-16mbps at -105dBm in Bay Ridge 

Low signal in my area in bay ridge today... Hopefully an upgrade finally!

I was right! 4G signal today.

What kind if internet speed do u have that it buffers so much? I just have 3 mbps basic broadband cable internet and can watch youtube just fine mind u that most if the time i have to watch it in 480p.

I have a 3mbps line too, but it's shared amongst 3 people with two devices each If anyone's doing anything on the internet at all, it's pretty much a guarantee that streaming anything will be impossible.

Do you have WiFi at home? If so, then there's really no need for WiMax or LTE at your home.

Yeah, but it's really slow. Can't watch youtube without constant buffering.

gah, still waiting for LTE here in lower bay ridge. I get signal pretty much everywhere I go, just not at home. Missing WiMax quite a bit now.

Also, isn't Motorola well known for its awesome antennas?

I think WiMax is awesome, but I'm really lucky. I can see the tower from my window here in Brooklyn, and usually get 10-15mbits in my room, though it drops down to 6-8 during peak times. That's still twice as fast as the crappy DSL we have at home, so I'm ridiculously happy.
