Help At&T Sim Card in Verizon Galaxy S5

[areyno8]

Hi,

A bought a used Samsung Galaxy S5 (Verizon) from a friend of mine to upgrade my older S4. His 2 year contract was up and he upgraded to the Galaxy S7 Edge. I did some research and I thought I could stick my AT&T sim card in the S5 and go about my business. I changed my network mode to GLOBAL and turned on my Global Data Roaming Access.

I thought everything was working great, but when I traveled to Galveston beach I realized I could only call and text people. Texting only worked about 50% of the time. No applications were working for example google maps, spotify, groupme etc. Everything worked when I was home because of the wifi connection.

So my question to the forum is can I use the Verizon S5 with my AT&T sim card?

If you're not in a Band4 area,it looks like it's 2G/3G only.

You may need to manually set the APN :
App Drawer > Settings > Mobile Network Settings > Access Point Names & insert the following:

I manually set the APN as instructed and I believe that solved the problem. Sometimes I see a 4G LTE logo (weak signal) and other times I see a H or H+. I am assuming the H and H+ is the slower 2G/3G connection?

Thanks for the help.

Glad to hear things are (apparently) working as they should.

I believe H/H+ stands for HSPA,which is 4G,not quite as fast as 4G LTE:

Thanks KOLIO,

I have another problem and I was hoping you could assist me with. I cannot get group messages or multimedia messages to work. I even did a restore to factory settings and it still does not work. I entered the APN settings as you previously directed and double checked that I did not fat finger any digits. Everyone else works great by the way.

When I do get a group message or a picture message, it will ask me to download the message. They are all small (1KB), but they never load.

I stumbled upon a similar thread where you helped the user out. How I knew to come back to you.

@areyno8

I use the messaging app Textra:

Set the MMS download limit to 1MB & you shouldn't have any problems,pix will show instantly.
Also,sometimes,in MMS settings,I have to toggle the MMS behavior setting from SYSTEM to LEGACY or vice versa.

Otherwise,this app is ready out-of-the box,works flawlessly 99.99% of the time & thankfully,the look/feel is customizeable.
