A basic phone with no internet access.

I would go with a GoPhone to avoid even the possibilty of Wifi as well as not having to pay for a data plan that you obviously would not use anyway.  The phone is $15 so no need to buy it used, you can get it from http://www.att.com/cellphones/att/z222.html#sku=sku6880347?CAGPSPN=pla&WT.srch=1

Thanks to both of you for your replies.  My son only needs a phone when he travels which is about 10 days out of the year so gophone is definitely the way to go.  I just found that you have to be very careful with the phone that you use.  Most phones today - even the $10-$15 flip phones - allow WiFi access.  You can block paid data use on the phone but if a phone allows for WiFi connectivity there is no way to block that access in public places where WiFi is free (i.e. airports).  I had to go with an older (used) phone to find one that did not have WiFi connectivity.  We had an old Pantech Laser laying around that worked.

Then I had to have AT&T block the data to the phone.  FYI for gophones they cannot block this in the store you have to call in and do it over the phone.  This was not explained to me and so the first trip with the phone my son was accessing data.  I gave AT&T an earful as I had carefully explained I needed data blocked and was told it was done.  They credited me the data charges.

I am not sure if the AT&T Z222 has WiFi capability or not.  In the specs it says it does but the salespeople at the AT&T store says it does not.  I had originally tried a $9.99 Tracfone from Walmart and was told that it did not have data access.  That information was incorrect.

Att doesn't make phones, they can only offer for sale what manufacturers make, and what the consumers will buy.  

It is almost impossible to find an entirely "dumb" phone, because that isn't what most consumers want.

Cheap z222 flip phone has limited access,( email access)  but if you use it on a Gophone account, can have data turned off on the account and put on a pay per use account.   The $2 per day Gophone account sounds like the way to go.  https://www.att.com/shop/wireless/gophone-plans.html

There is no way to turn off data on a postpaid account.

The only other option is to find a very old cell phone.  The problem is finding one old enough to not have Internet, but minimum 3G.   2G phone access is being phased out this year.

Yes, need a simple phone with text only, NO WEB, NO Camera!  This is what all of our tweens and teens need, NOT a smartphone.  Advice or suggestions please, i refuse to have my kids enter the current cesspool. Why are phone manufacturers holding everyone hostage.....ya, I know, MONEY!

@busymom4  The market for such a device is tiny, no money in it.

The Snapfone EZ 3G might do the trick, but you have to buy from the manufacturer.

It does have a camera.
