S4 won't connect to 3G/4G network - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hi Guys..
I unlocked sim card on my SPH-L720 but it won't connect to any network except to 2G network. I live in Venezuela and It's supposed to get 3G signal with my carrier.. but only network I can use is 2G..
Is there any chance to force 3G connection trought service mode??

Did you set/add your APN manually? That usually has fixed the problem for me.

APN settings

hi guys, what path do you need to follow so i can enter the APN settings for 3G. and when the 3G button changes to H, this means it's using HSDPA ?
Settings--->More--->Connections-->Connections.
Yes, "H" means HSDPA
didn't manage to find it.
But to use 3G you don't need it i guess.
So i got 3g enabled by the carrier, and my mobile is showing 3g. why isn't it working :S?
These settings are for using Internet, not for calls.
3G = Video Call enabled
i got 3g to work. however sometimes it uses GPRS. how do you disable it (No data doesn't actually work)

Telcel + HTC Aria = No 3G?

Hi guys,
I just bought this phone, unlocked it and inserted my sim everything was fine until... I noticed the "edge" icon.
It wont connect to the Telcel 3G network, I know that this phone is for AT&T network but Telcel uses the same frequencies (UMTS 850/1900), I tried "forcing" it to WCDMA only but it wont find any Telcel network.
What can I do? Does anyone have experience with this kind of problems?

Aria comes with APNS setup for AT&T data only. It's a simple fix - you can manually enter the info under wireless settings to add access point data for your carrier or you can just root and flash CM6, with has a huge - enormous default APNS database.
Here's a link to how the same issue was solved on the Nexus One.

Thank you! I'll try this right now!
-------EDIT-----------
Ok I entered the APN info, restarted the phone and Edge Icon is still there, with the "settings" on *#*#4636#*#* I changed to "WCDMA only" and the phone cant find a telcel network, only movistar, What is the problem? Maybe there isnt a Telcel 3g network near my phone? I used to have an iPhone 3G and I never had a problem with 3G Any thoughts?

This works perfectly.
My wife's Aria went into some factory reset and lost 3g, now it's back thanks to this.

[Q] 3g issues

Im having trouble connecting to 3g.
My Xplay connects to H network fine, but when that drops out it only connects to 2g.
When i manually try to select 3g im given a pop up 'your sim card doesn't allow a connection to that network'.
Ive phoned my provider & they say it's not sim related & there's no problem with the network.
Any suggestions?

Same issue here. But mine does go into 3G mode. But when i try to register for 3G it gives that error.
Most likely a frequency incompatibility. Not sure what H is, but check the gsm frequencies from the SE website and compare it with the 3G/HSPA frequencies your carrier runs on.
its a frequency issue, the only fully working networks are in the uk
I am in the in the UK !
same here, i did yesterday see my signal go from H to 3g but only for a few seconds. I am connected to vodafone uk and live in the city center where 3g always is available, how come mines mainly displaying H am I missing some settings ? does anyone elses xperia play show 3g in the taskbar ?.... tanks in advance
H is faster think of it as 3.5g

It depends on many things. Maybe you should have enabled "Only 2G" on Settings>More>Mobile Network. Also, it could be that there is no good coverage where you live, so is always changing to 2G.
