Who is this guide for?
This will be the last update to this tutorial until 5.x firmware is released. I
am not renewing my Simple Mobile plan as I can't afford the monthly expense.
- iPhone 4 owners (already activated)
- 4.0 or 4.0.1 firmware
Simple Mobile resells T-Mobile's service and is yet another option to having to use AT&T on your
iPhone 4. You can check out their site
They only have three plans and
their best deal is the $60 a month for unlimited everything: nationwide talk, text and web. This is
a month to month service plan. No messy applications, just purchase the SIM and activate it online.
Many retail stores carry these SIMs as well. Data, tethering, MMS (except receiving images) and
FaceTime all work.
Simple Mobile's 3G network frequencies are NOT compatible with the 3G radio built into the
iPhone. You will NOT receive 3G service from Simple Mobile. You can surf the 'Net using EDGE
service, but it's slower. No, there is NOTHING you can do to fix this!
I'm sure there are many ways to do what I'm going to demonstrate. This is what worked for me.
First I jailbroke and unlocked my iPhone 4 using
Notes for those on 4.1 firmware. I don't know if I will update this tutorial beyond these brief
notes. Here are some issues I came across when using 4.1 firmware via the limera1n jailbreak:
MMS doesn't send or receive photos for me. I not only tried manually entering the settings, but also
used the T-Mobile US MMS Fix on Cydia.
MiTime does not support new FaceTime activations on 4.1 firmware at present. You may want to try
Tango Video Calls, available in the App Store.
First activate your Simple Mobile SIM here:
https://myaccount.mysimplemobile.com/WSC/sm_activation.jsp I couldn't do this using
Firefox, and had to use Safari. Firefox doesn't play well with their form.
My iPhone was activated with an AT&T SIM. You can also use unactivated AT&T, Cingular, GoPhone,
H2O, Net10, or O2 SIMs to activate the iPhone. Here's my iPhone after being restored with a
GoPhone SIM. The 3G is misleading as there is no data connection.
Remove your activation SIM and install the Simple Mobile SIM (which you have already cut down to the
proper size).Switch out your SIM card.
I've already jailbroken with Jailbreakme.com and have used Cydia to install ultrasn0w so I am
unlocked. The Simple Mobile logo appears immediately. If it doesn't try ejecting and reinstalling
the SIM or rebooting the iPhone. The text carrier logo can be changed for a logo that fits, or
for a graphical logo. I'll cover this later. At this point you should be able to make and receive
Launch Settings, press General, then press Network.
Make sure that enable 3G is turned off, cellular data is on and data roaming is off (you may need
this on). Next we need to make a new menu button appear. The only way I have found to do this
easily is to eject the SIM card and reinsert it while this screen remains open.
It can take up to a minute to regain your signal. You might have to do this more than once.
I've noticed on reinstalling the Simple Mobile SIM it is susceptible to the invalid sim / sim
failure message. This could also require a respring or reboot. Once the button Cellular Data
Network appears press it.I've heard that a program on Cydia called Advanced Preferences can also
make this hidden button appear.
The cellular data page will be empty. You need to enter some data into the various fields. Just
press the field you want to enter data into.
MMS Proxy: 216.155.165.050
MMS Max Message Size: 1048576

I then shut off the Wi-Fi on my iPhone to test EDGE data access. It worked right away. Then I
set up tethering. Launch Settings, press General, press Network then press Internet Tethering.
Slide the slider to the on position. I selected USB Only at the pop up message.
One of two things should happen: you'll receive a pop up message telling you that a new network
interface has been detected. If this happens then click the Network Preferences... button.
Otherwise launch System Preferences yourself. Click on Network in the Internet & Wireless section.
Click the + button just above the lock at the bottom of the screen.
You should receive this pop up. Everything was already selected for me in the boxes. Click the
The iPhone will now appear in the list on the left. I selected the iPhone and then clicked the
Apply button in the lower right corner.
The iPhone moved to the top of the list and connected.
When you are tethering a blue bar appears on various screens on the iPhone so you don't forget.
My Mac is now tethering.
Shut off tethering when you are done. You can monitor your data consumption by launching Settings,
pressing General, then pressing Usage.
