I have an I-PHONE 6PLUS, HOW DO I GET IT TO PING OFF VERIZON TOWERS INSTEAD OF AT&T

Unlocked refers to removing software that keeps a phon e"locked" to a specific service provider. Sounds like the phone you have is on a carrier that has poor coverage in your area. I would suggest contacting the provider of your phone to see if they can either 1) update the phones info so it can access other towers (for example - just because it is on Verizon doesn't Mena it is programmed to access all towers as towers are used by contract and towers are often updated) 2) provide you with a phone that is on a different carrier that has better coverage in your area.

The only way to change to a different tower is to change phone AT&T carrier to Verizon carrier. The unlock code is your password. There is no unlock code to change towers. You have to cancel service at AT&T and start service at Verizon.

Here's a place that has a list of 10 different ones you can look at

put in a support ticket on straight talk's facebook page. sounds like your phone needs to be reprogrammed.
also make sure that you have good native verizon coverage, because straight talk verizon phones use only
verizon towers and are non roaming.

i dont think so because straight talk has there own company. thats why walmart is the only one who sells their refill cards. that's like since they use verizon towers you can take a straight talk phone and change it to a verizon service but you cant take a verizon phone and change it to straight talk.

there isnt one its a verizon wireless cell phone which is cdma technology no sim care they use cell towers not satellite and sim to activate it dial *22899 or *22869

Your work laptop probably has proxy settings in the browser. If yes, please remove it adn try. That should help .

You may not have coverage in your area unless your roaming, call your cellphone carrier and ask if you have service at the location! if you do you may have an issue on your carriers end, call tech support and ask whats going on.
If you can make calls whilst roaming, there should be no reason you can't when on your normal carrier.

Call verizon. They should be able to direct you. Good Luck.

Every phone company has its own hardware to connect with their cell phone towers. You cant just switch a phone between service providers. You have to get a phone that was designed for that provider. If it says verizon wireless, it is for verizon wireless only.
