Post [Q] Sms a lot quicker on 2G/3G than on 4G, why?

Hi! If I have my Nexus 5 in 4G, everything works great and fast, except the sms that take about 1 minute to being sent when they are a little big (4 or 5 parts). But on 3G, the big sms are sent right away, only take a few seconds like usual. I know thats not a network problem because I had the note 3 before and everything worked fine on 4G, the sms were sent very fast. Can this be a software problem on the Nexus 5?

Not disputing your findings but just know that LTE is a DATA only application now. So even if you have "LTE" displayed up top, you are still using the WCDMA (AKA 3G) air interface to send SMS.

Why it would send faster if LTE data is disabled i have no idea. The SMSC stays the same on either one so it shouldn't matter.

That's my question, why its a lot faster in 3G, I don't understand this because makes no sense. I want to enable 4G but annoys me that takes so much time to send a sms. But can this be a software problem? Or hardware? I don't know if I should return my device or not.

I believe it has to switch from LTE to 3G/H/H+ to send the sms. It only has 1 radio chip with 1 antenna. So you can only use 1 radio at a time. I have noticed when watching my phone while sending SMS, that LTE switches to 3G/H/H+, then the SMS sends, then LTE comes back.

Because SMS isn't sent using 4G. If you're on 4G, it switches to 3G in the background to send the SMS.
Same for a voicecall. Your phone will switch to 3G. LTE is data only.

your solution: turn off lte.

thats the only way to solve the issue you are describing.
Go back to stock on your nexus 5 using this guide: here

Tired of paying too much money for your phone plan? go prepaid!

Save money on refills for your prepaid plans: Use Callingmart

But can this be a hardware problem? Should I return my phone? I want to be able to enable LTE and do everything fast, like I have done with other phones and everybody does, this isn't suppose to happen, right? I have a 4G phone and its like a 3G one, I think you understand my frustration.
