How to Activate an Ultra Mobile SIM Card

How to activate Ultra Mobile SIM card

This post will walk you through the process of activating your Ultra Mobile SIM card. A SIM card is typically activating with a new number or with a transferred number form another carrier. Either option you choose, this post will guide you through the activation process.

Please note that Ultra Mobile offers two types of SIM cards.

  1. Regular SIM card ( purple ). Requires payment for the first month of service in advance
  2. Preloaded SIM card ( orange ). Equipped with the first month of service. No required payment upon activation.

The activation process for the two types of SIM cards differs slightly. Activating a preloaded SIM card is faster because it comes equipped with the first month of service; therefore, payment is not due until next month.

Activate Ultra Mobile SIM Card

We will start by activating Ultra Mobile’s purple SIM card online, or you can 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, 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 a new number

On the next page, you will have the option to activate your Ultra Mobile SIM card on a new number or transfer your existing number. Preparation is key for this step. You will need your account number and password before you start the activation.

4. Select a monthly plan

Ultra Mobile plans monthly plans range between $16 and $49. Currently, Ultra Mobile does not have pay-as-you-go plans. However, prices and plan features change frequently.

5. Choose your area code

Your area code is 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. Entering the zipcode 93257 will result in a 559 area code and so on.

6. Pay for your first month of service

Since we are activating a purple SIM card, a credit card is needed to successfully activate the Ultra Mobile SIM card.

7. Program your data settings.

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

How to Activate Preloaded Ultra Mobile SIM Card Online.


Activating a preloaded SIM card is as simple as it gets. Ultra Mobile preloaded SIM cards come equipped with the first month of service. They are priced based on the preloaded monthly plan, usually at a discounted price of up to 80% off. These discounted SIM cards are great for someone skeptical who is mainly interested in trying out the service.

We will walk through the process of activating a preloaded (orange) SIM card online.

1. Choose the Orange SIM option

Just like the purple SIM card, go to 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. Providing your zip code determines your area code, so make sure you use a zip code that is within the area code you of your choosing.

For example, zip code 93256 will generate a 559 area code, a 93215 zip code will generate a 661 area code.

4. Program data settings

Programming the data settings is a breeze!

Activate Ultra Mobile Preloaded 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 the SIM card in the SIM slot
  6. Program data settings (This option applies to T-mobile and unlocked GSM phones only)

In some situations, 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.

Answering Comment Based Questions

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

It is not possible to transfer an existing Ultra Mobile SIM phone number to a preloaded SIM card. Ultra Mobile (and other service providers) have preloaded SIM cards to attract new customers.

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?

According to an Ultra Mobile representative, it is possible to transfer your non-Ultra Mobile phone number to a preloaded Ultra Mobile SIM card.

Program Ultra Mobile Data Settings

Program Ultra Mobile APN settings

Ultra Mobile has made it easy 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.)

Follow the steps to automatically program your APN settings.

  1. Go to
  2. Enter your phone’s IMEI number. You can find it by going to settings-about
  3. Choose your platform Andriod, IOS, or other
  4. Enter your phone number. You should receive a text message containing a link to an app. Click the link and download the app. Follow the in-app instructions.

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.

Follow the steps to program your APN settings manually.

  1. Go to
  2. Enter your devices’ IMEI number (dial *#06# on your phone’s keypad to retrieve your phone’s IMEI number)
  3. Click on “Lookup 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 online. The option is just below the “Lookup IMEI” button.

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

Transfer Number to Ultra Mobile (port)

Before you can transfer or port your number to Ultra Mobile, it is required that you obtain your account information from your current service provider.

Important! Don’t cancel your service till the transfer is complete. Doing so results in a failed port. Only cancel your old phone service once the transfer is complete. That is a common reason phone number ports fail.

The information needed to transfer your phone number to Ultra Mobile depends if you are on a prepaid plan or a type of contract.

This is 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 transfer and activate your Ultra Mobile SIM card.

Information such as your first and last name and address are only optional. Don’t feel concerned if your current service provider doesn’t have that information on file.

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 the information ready, you can start the process of transferring your number to Ultra Mobile.

To avoid a delay in transferring your existing number to Ultra Mobile, all the information that you provide must be correct. The information you provide is verified. Any mismatch will result in a failed transfer. Failed transfers are resolved by re-providing accurate information.

The information needed to port a phone number to another carrier applies to all activations, whether online, over the phone, or at a retail location.

Ultra Mobile Compatible Phones:

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

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

Does Ultra Mobile charge an activation fee?

Ultra Mobile 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 or by calling 1 (888) 777-0446.

my service is disconnected, would I be able to use my old SIM card for a new activation? Thanks
I have bought a preloaded 1 month ultra mobile sim card (orange). Can I activate it in my country before go to the destination? What if I dont't enter a zip code during activation, will it also give me a new US phone number? Is it just insert the sim card at the arrival and it will get work automatically?
The preloaded SIM card you are trying to use abroad only works in the USA.
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
It means, that when I used my Simcard last summer, I can not use it and activate it again ? Thank you
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.
I am already on ultra mobile network, can I activate a prefunded sim for the same number?
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
does ultra mobile still have preloaded sim card
I recently bought one from Ebay.
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? Thanks
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
I bought a preloaded ultra mobile Sim card but they sent me a unloaded one what do I do about that?
You should return it. How much did you pay for it?
That's why, Straight talk phones are carrier locked
The phone? It was a black Friday special 20.00 I like the phone but I don't want straight talk
Can I activate a new straight talk phone with simple mobile? I know I did it the other way I bought a simple mobile phone ativated it paid one month the next month I got a st right talk refill card and switched it over and didn't realize it until it was to late.
I have a simple mobile sim card for a T Mobil phone but when I put it in the phone it said invalid sim
Could it be that you your T-mobile phone is under contract?
I did not understand one point about the purple SIM. I have to pay when I buy it online and then pay again for the plan when I activate the SIM? That is, do I have to pay 2 times?
When you activate your sim card, you pay for the first month of service. So, you are only paying once.
I activate my sim card at a gas station near where I live and they charged me $20 to activate my service. I hate rip-offs!
Yea, same. It's best to do it online
I bought an Ultra Mobile sim card that was already active on another line. What should I do?
