Walmart Family Mobile

Was messing around with some old iPhone 4s and Walmart Family Mobile since my parents wanted the phones and wanted the cheapest phone bill they could get. I found various how-tos on the web and tried to combine what I found into one set of sensible instructions. Hopefully in the future things won't be like this.

First of all you need to be prepared to cut a SIM down to micro size since so far Walmart Family Mobile is supplying SIMs in only the large size. Cutting them can be done with scissors or an exacto knife and there are plenty of instructional sites and videos out there that will show you what to do. But there are some cheap devices (imagine a ticket puncher) which will punch a micro SIM out for you so if you can borrow one or don't mind splurging ten dollars I'd recommend that.

After getting the SIM activated you want to make sure you can actually use the "unlimited texts and unlimited data" that they advertise. Walmart Family Mobile runs on T-Mobile's network so don't expect 3G speeds until and if T-Mobile changes their 3G spectrum. But you can still use Edge. A good many internet postings deal with getting data and MMS messaging set up correctly on "other" phones not officially supported by Walmart Family Mobile. This is a summary of what I found. Some of it was culled from the Walmart Family Mobile support page. But some of it did come from various other forums and comments.

First go to Settings>General>Network>Cell Data Network

Cellular Data

Username: leave blank
Password: leave blank


Username: leave blank
Password: leave blank
MMS Proxy:
MMS Max Message Size: 1048576

Leave all other fields blank.

After doing this, you might need to go to **Settings>Messages** and turn on MMS Messaging. I suggest restarting the phone also.

Some notes:

The majority of posts had the max message size as 1058576. This just didn't make sense to me as it was not a power of two. One post I found said 1048576 which is a power of 2 so I went with that.

  • is listed as a gateway address on the Walmart Family Mobile support page and not a proxy address.
  • is an alternate gateway.
  • is listed on the Walmart Family mobile page as a proxy address but my experiments with it seemed to cause failures in sending MMS messages.

Also some suggest this field should not be blank but this url instead:
