Can I use an unlocked Verizon Galaxy S5 with AT&T
Well I have a friend that wants to sell me her Galaxy s5 but its on Verizon. She unlocked it already because she was overseas in Korea but got another phone. Would I be able to put a SIM card in it and use it with my AT&T plan?

Hi ashleyamia,
You should be able to use the Verizon S5 with AT&T. You will not get LTE coverage with it as the LTE bands supported by Verizon are not the same as AT&T.
I would pop your SIM in first to see if you get any coverage at all as sometimes Verizon and Sprint "lock" the GSM side (the radio that would allow you to connect to AT&T) from being used on US Carriers at the firmware level.
If it does work you should visit an AT&T Company store or contact Customer Care to update your IMEI so you have the proper data plan for the S5.
You may also need to program your own APN setting for the device. I have listed them below in case you need them 🙂
Name - PTA
APN - pta
Proxy - Leave Blank
Port - Leave Blank
Username - Leave Blank
Password - Leave Blank
Server - Leave Blank
MMSC - http://mmsc.mobile.att.net
MMS Proxy - proxy.mobile.att.net
MMS Port - 80
MCC - 310
MNC - 410
Authentication Type - Leave Blank
APN type - default,mms,supl,hipri
Bearer - Leave Blank
If there is any settings that are not listed here leave them as default. You will need to hit the menu key and then save after inputing all the information. Otherwise you'll have to retype everything. You may need to restart the phone once you put the APN in.
Hope this helps!

NO verizon phone is locked period. It was part of the 700c block auction when verizon first started LTE. Know you will get a pop up every so often telling you that a sim card in there is not verzions. But the phone works fine. I used a droid dna for a while till the one came out

Thank you for the help, but my research has me wondering about your lte bands.
AT&T: GSM+LTE, 2G/3G: 850MHz & 1900MHz, 4G: 700MHz, 1700MHz/2100MHz
Verizon: CDMA+LTE, 2G/3G: 850MHz & 1900MHz, 4G: 700MHz, 1700MHz/2100MHz (planned)
what do you mean by not working lte? frankly, my att s4 does not work lte either, so it would be nice see what you have for the att and verizon bands. I get lte when I power on, then never lte again, this again is a att purchased s4 with att sim.
also, it seems to me that we would have 4g support moving from vzw to att with s5, but not 2g and 3g.
please help me understand as I am in need to move an s5 to att. I see some do it on youtube with no problem, but then I read posts like yours.
thanks.

http://en.wikipedia.org/wiki/List_of_LTE_networks
the MHz can match but the band may not as there are bands in the ranges of the MHz
if your not seeing lte in your area either you switched from and Iphone and your data plan was not changed. Apple has different coding in att's systems

The us is a weird beast when it comes to cellular in the first place. They only phone I know of that works on multi carriers is the Nexus 5. It will work on tmobile sprint and att out of the box. I know I have one I made best buy price match the playstore on. There all the same model number in the us.
