How to Activate Ultra Mobile SIM Card

How to activate Ultra Mobile SIM card

Activate Ultra Mobile SIM card with a new number or by transferring your existing number–the process is simple.

Which SIM card do you want to activate?

  1. Regular SIM card ( purple ) that requires you to pay for the first month of service in advance
  2. Preloaded SIM card ( orange ) that is equipped with the first month of service.

The activation process for a preloaded SIM card is faster. You won’t need to pay for the first month of service because it is already included.

Activate Ultra Mobile SIM Card

First, let’s take a look at how to activate Ultra Mobile SIM card online (purple).

Skip to activating preloaded SIM.

You will have the option to get a new number or port (transfer) your existing number at a later step in the activation.

1. Visit Ultra Mobile’s activation page

Start by going to https://my.ultramobile.com/activation, and choose the purple SIM card option.

2. Locate the 19 digit ICCID number

The ICCID number is located on the back of the SIM card, just below the barcode. Enter that number in the ICCID  input field and hit the “Start or Resume your Activation” button.

3. Transfer or get new number

On the next page, you will have the option to activate Ultra Mobile SIM card with a new number or transfer an existing number. So, you might want to get your account number and password before you start the activation.

4.  Select a plan

Ultra Mobile plans start at $19 and end at $49. Currently, Ultra Mobile does not have pay-as-you-go plans. The $45 plan has the most data!

5. Choose your area code

Your area code will be based on the zip code you provide. For example, if you want a 599 area code, enter a zip code that is within the 559 area.

6. Pay for your first month of service

Furthermore, you will need a credit card to successfully activate Ultra Mobile SIM card.

Ultra Mobile activation fee?

Ultra Mobile itself does not charge an activation fee; however, some unauthorized retailers do. You can avoid paying an activation fee by activating your SIM card on Ultra Mobile’s website.

7. Program your data settings.

Finally, the last step is to program your APN data settings so you can access the internet (it isn’t as complicated as it sounds).

Moving on…

How to activate preloaded Ultra mobile SIM card online.


Activating a preloaded SIM card is a little different (faster) than activating a purple SIM card. The difference is that a preloaded SIM card is already equipped with the first month of service; therefore, you won’t need to use your credit card to pay for anything. All you need is the SIM.

1. Choose the Orange SIM option

Just like the purple SIM card, go to https://my.ultramobile.com/activation and select the orange SIM card option.

2. Find the Act Code

On the back of the SIM card, you will see a faded area. Scratch it off to reveal the Act Code and enter it in the Activation Code field. Finally, hit “Start or Resume Activation”.

3. Choose your Ultra Mobile area code

On the next page, enter your zip code. This will determine your area code, so make sure you use a zip code that is within the area code you of your choosing.

For example, a zip code of 93256 will generate a 559 area code, a 93215 zip code will generate a 661 area code and so on.

4. Program data settings

Programming the data settings is a breeze!

Alternatively, you can activate the preloaded Ultra Mobile SIM card using the automated phone system.

  1. Dial 888-899-0820
  2. When prompted, enter your Act Code located on the back of the SIM card
  3. When prompted, enter your zip code. Your area code will be based on the zip code you provide.
  4. Write down your phone number
  5. Insert your SIM card in the SIM slot
  6. Program data settings (This option applies to T-mobile and unlocked GSM phones only)

In some situation, the activation process may take up to 30 minutes. In such a rare situation, hang up the phone and insert your SIM card in the SIM slot. Power on your phone and wait for a confirmation message.

Abhay Asked:

Can I activate a preloaded SIM for the same number if I am already a customer with Ultra Mobile?


If you already have service with Ultra Mobile, then you cannot buy a preloaded SIM card and transfer your Ultra Mobile number to it, you must get a new number.

Ultra Mobile (and other service providers) have preloaded SIM card to attract new customers. So, another question is:

What if I’m with a different carrier and I want to switch to Ultra Mobile. Can I transfer my number if I wanted to use a preloaded SIM card?

I don’t have an answer to that yet, but I will post it as soon as I do. So, I just got in touch with an Ultra Mobile customer service representative and it turns out that it is possible to transfer your non-Ultra Mobile number over if you’re using a preloaded SIM card.

Ultra Mobile Data Settings

Program Ultra Mobile APN settings

Ultra Mobile has made it extremely simple to program the data and MMS (APN) settings on your device.

They have a tool on their website that does all the heavy lifting for you. (Some phones are not compatible to use this tool.)

The process:

  1. Go to https://ultramobile.com/data-settings
  2. Enter your phone’s IMEI number. You can find that number by going to settings->about
  3. Choose your platform Andriod, IOS, or other
  4. Enter your phone’s phone number. You should receive a text message containing a link to an app. Click on that link and download the app.

If your phone does not support automatic settings, you will need to program the APN settings manually, but don’t let that scare — it’s really easy.

To do this:

  1. Go to https://ultramobile.com/data-settings
  2. Enter your devices’ IMEI number (dial *#06# on your phone’s keypad to retrieve your phone’s IMEI number)
  3. Click on “Look up IMEI”
  4. Use the information that is given to navigate to your phone’s APN settings.
  5. Enter the required information in the appropriate fields.

Alternatively, you can look up your IEMI manually. The option to do that is just below the “Look up IMEI” button.

On the next screen follow the steps to navigate to your phone’s APN and MMS tap and enter the information provided.

Transfer Number to Ultra Mobile

Before you can transfer your number to Ultra Mobile, you will need to get your account information from your current service provider.

Don’t cancel your service till the transfer is complete. You will lose your number forever if you do. It will be safe to cancel your old service once your phone number has been successfully transferred to Ultra Mobile.

The information that is needed depends on whether you are on prepaid plan or a contract.

What you will need if you are on a prepaid plan:

  1. Account number
  2. Account password
  3. Phone number

Call your current service provider to obtain this information and to successfully activate Ultra Mobile SIM card.

Information such as your first and last name and address are only optional and not required, so don’t freak out if your current service provider doesn’t have that information.

If you are on a contract, you will need:

  1. First and last name
  2. Address
  3. Account passcode
  4. Phone number
  5. Social security number

The easiest way to get your information is by calling your service provider. Once you have this information ready, you can proceed in transferring your number to Ultra Mobile.

In addition, to avoid a delay in transferring your existing number, all the information that you provide must be correct.

Keep in mind that the account information needed to transfer a number over to another carrier applies to all activations — online, over the phone, or at a store.

Ultra Mobile Compatible Phones

T-Mobile branded or GSM unlocked cell phones will work just fine on any Ultra Mobile plan.

Also, carrier locked GSM cell phones can be used for just talk and text. Consequently, the data will not work unless the phone is unlocked or T-mobile branded.

my service is disconnected, would I be able to use my old SIM card for a new activation?


Unfortunately, that is not possible since you can only use one SIM card per activation. You can find these SIM cards for cheap on EBay or Amazon

Lucia Misunova

It means, that when I used my Simcard last summer, I can not use it and activate it again ?
Thank you

That is correct. You would need to get a new SIM card.


I have bought an Ultra Mobile “Data Plus” card with pre-paid of $34 for one month service. Following the instruction (attached with the card) for Data Setting for my Android phone, I have problem for the “MCC” and “MNC” setting that the instruction asks to leave them blank but the device requires for an input of 3 digit for “MCC”; and 2 digit or 3 digit for “MNC”.
I am unable to set the phone leaving the MCC ad/or MNC blank. Do you know what number I shall input for these items ? Thanks.


What make and model is your Android phone?


I am already on ultra mobile network, can I activate a prefunded sim for the same number?


Unfortunately, that is not possible on prefunded SIM cards.

Marc Lanteigne

How long is the expiry period between the purchase of a new prepaid SIM card and it’s activation?


Hello Marc,
If you bought a new SM card and never used it before then it will never expire. However, if you have activated the SIM card and did not renew your service for a period of 60 days then the SIM card does expire.

I hope I answered your question, Marc

Antonio Whuerta

does ultra mobile still have preloaded sim card

Fabian Amran

They still do because why would they give you the option to activate a preloaded sim card if they don’t have them.


Sometimes there are discounted Ultra Mobile SIM Kit. If I want to keep my existing Ultra Mobile number, can I buy these SIM Kit, and use Port-in option to transfer my current Ultra Mobile number to the new SIM? or the only option to keep my existing Ultra Mobile number is to recharge on the old SIM?


I am going to assume that you mean prelaoded SIM cards when you refer to “Mobile SIM Kit” because it wouldn’t make sense to go through all that trouble for a regular SIM card.

If your purchasing an orange SIM card (preloaded) then no, that is not possible.


At Ultra Mobile, we do not charge an activation fee and our customers do not have to sign any contracts!


I am a tourist and have bought a $34 preload 1 month sim card from online shop, can i do the activation step in my home country just before i come to US. How and I know my sim card phone number in my case?


You can!
However, if you’re not sure how to activate your preloaded SIM card, you can go to Simple Mobile’s website and chat with a representative. You’ll need to have the SIM card in your hands, though.

Just go to their website and wait for the chat button to pop up. You’ll need to do this during their business hours, which are 8 AM – 11:45 PM (EST) 7days a week.

Your other option is to call them at 1-877-878-7908
