You can view your bills, manage payments and more through your My AO Mobile account here.

You can add up to 9 additional SIMs through your My AO Mobile account here. Just let us know who they’re for and we'll do the rest.

Every SIM you add to your account will be £6 cheaper than full price. You can add up to 9 extra SIMs meaning savings for the whole family!

Your AO Mobile plan covers everything you need day to day, but if you ever go over your allowance, a spend cap makes sure there are no surprises on your bill.

Yes, at any time. Pause, remove or adjust it through your My AO Mobile account.

1. To change your spend cap:
2. Log in to your My AO Mobile account.
3. Go to “Plan & Add-ons”
4. Select “Spend cap”
5. Choose your preferred limit or set it to £0 if you don’t want to spend anything beyond your plan.
6. Save your changes. Your new cap will update almost immediately.

The maximum spend limit is £40 per SIM.

We’ll also send you alerts if you’re getting close to your limit, so you stay in control at all times.    

Charges covered by the spend limit may include:

• Calls, texts and picture messages outside your allowance
• Calling abroad
• Roaming outside your allowance
• Access charges for premium numbers (09, 118, 084, 087, 070)

A small number of things sit outside it:

• Your monthly recurring charges e.g. plan charges
• Any add-ons like roaming bundles
• Service charges for premium numbers (09, 118, 084, 087, 070)
• Admin charges and late payment fees

Great question. If you’re travelling abroad or are close to the border of another country, your phone may connect to a foreign network without you realising. To avoid accidental roaming charges, you can turn off roaming completely by:

On iPhone:

1. Go to Settings
2. Select “Mobile Data”
3. Select “Mobile Data Roaming Off”
4. Turn data roaming off

 On Android:

1. Open Settings
2. Select “Network & Internet or Connections”
3. Select “Mobile Network”
4. Turn data roaming off

You can keep track of your data usage at any time through your My AO Mobile account here. This helps you stay in control of your allowance and avoid unexpected charges. Most smartphones also show data usage:

On iPhone:

Go to “Settings” and then “Mobile Data”
Scroll to see usage per app

On Android
Go to “Settings”, then “Network & Internet” and then “SIMs / Data Usage”
View total usage and usage per app

Yes, we’ll send you notifications via text when you reach key points, like using 80% of your data and 100% of your data.

If you’re receiving unwanted calls or texts, you can block the number directly from your phone. Once blocked, that number won’t be able to call, text, or FaceTime you.

On iPhone

1. Open the Phone app
2. Select Recents
3. Find the number you want to block
4. Tap the “i” icon next to it
5. Scroll down and tap Block this Caller

For texts:

1. Open the message
2. Tap the contact name/number at the top
3. Tap the “i”
4. Select Block this Caller

On Android (Android menus vary slightly by brand, but the steps are similar.)

To block a call:

1. Open the Phone app
2. Go to Recents
3. Tap the number
4. Select Block or Report/Block

To block a text:

1. Open the Messages app
2. Open the conversation
3. Tap the three dots menu
4. Select “Block number” or “Details” and then “Block & report spam”

If you’re receiving unwanted or spam calls/texts, there are several easy ways to block them and reduce how often they reach you.

1. Block the number on your phone. This prevents that number from contacting you again.

On iPhone:

Open the Phone or Messages app
Find the number
Tap the “i” icon
Select Block this Caller

On Android:
Open Phone or Messages
Tap the number or conversation
Choose Block or Block & report spam

2. Register with the Telephone Preference Service (TPS)

TPS is the UK’s official “Do Not Call” list for stopping unwanted sales and marketing calls. You can register for free by:

Texting “TPS” and your email address to 85095 or registering online via TPS

This won’t block scams, but it will reduce legitimate marketing calls.

3. Report spam texts. If you receive a suspicious or unwanted text, forward it to:

7726 (spells “SPAM” on your keypad). This helps mobile networks block the sender.

4. Turn on phone spam protection. Most phones have built‑in filters.

On iPhone:
Go to Settings, then “Phone”, then “Silence Unknown Callers”
This sends calls from unknown numbers straight to voicemail.

On Android:
Go to the Phone app, then “Settings”, then “Caller ID & Spam” and then “Turn on spam protection” This can significantly cut down nuisance calls.

5. Be careful where you share your number. It’s a good idea to avoid putting your number:

In online forms unless necessary
On social media
In competitions or marketing sign‑ups

This reduces how often your number enters marketing lists.

Setting up your voicemail is quick and easy. Once activated, callers can leave a message when you’re busy or can’t pick up.

Dial your voicemail number. This is 121 from your AO Mobile phone. Most phones use the same shortcut.

Press and hold 1 on your phone’s keypad. This will connect you to your voicemail service.

Follow the spoken instructions. You’ll usually be asked to:

• Set a voicemail PIN
• Record your name
• Record your personal greeting
• Once done, your voicemail is ready to use!

To check your voicemail messages, just call 121 from your AO Mobile phone and your message or messages will play automatically. At the end of your message, you'll be given options to listen to it again, delete it or call the person back. You can also skip to the next message or save the message.

You can check your messages from any phone at home or abroad if you have previously set up a PIN for your voicemail. Just call +44 7836 121121 and follow the instructions.

You'll have 3 attempts to enter your voicemail pin successfully before it gets locked. If your voicemail account does get locked, you'll need to contact us to reset it.

We’re sorry to hear that! You have a 14-day cooling off period to change your mind when you buy your AO Mobile SIM. If you change your mind after that, you’ll then need to give us 30 days’ notice, which will incur charges.
