Hi @Colland61 ,

it’s either the SIM or your device. The easiest way to determine the problem is insert the SIM into another device or insert another SIM in your current device.

If the problem follows the SIM then you need a new SIM that you can purchase at any mobile store, online (Amazon or other sites), or at a Bell store.

If the problem stays on your device with another SIM, then you would need more troubleshooting. Let us know the outcome.

Hey, 

I stay in Etobicoke and for some reason, my phone says no sim..even when the sim is inside. What could be the issue with this?

Good Day & Welcome to the Bell Community Forum.

There can many different reasons as to why your phone indicates an invalid or no Sim condition. What is the make & model of your device?

Please check out the following:

1. Have you fully powered your device off & on?
2. Is your iOS / OS & your apps up to date?
3. Have you removed & reinserted your SIM? Make sure the SIM is fully inserted & the door is closed
4. Have you tried your SIM in another device?
5. You can try using a different SIM in your device. If you don't have one, visit a Bell store and ask them to test with another SIM card. You may need a new SIM card.
6. Are you able to connect to the Wi-Fi?
7. Any physical damage that you can see on your mobile device?

Let us know if we can be of further assistance.

Take care.

I can't activate my sim or eSIM ? Bell doesn't  even turn up as my service provider.

Good Day & Welcome to the Bell Community Forum.

Thank you for posting your question. In order to assist you further, we need for you to provide us with a lot more detail. This is a peer-to-peer web site. We do not have access to your accounts & billing details.

You mentioned that: "Bell doesn't even turn up as my service provider.". Have you verified that your account is activated on MyBell?  Have you rebooted your device?

Please explain exactly what it is you are trying to do & how you are going about activating your SIM & eSiM.

1. Is this a new Bell Mobility account?
2. Which Bell Mobility plan do you subscribe to? Are you on a monthly or pre-paid?
3. Did you purchase this device Bell or from another supplier? E.g. Apple, etc.
4. Are these devices locked to a different carrier?
5. Are you on a SmartPay 2-yr. contract or BYOD plan?

If you are transferring to a SIM card, take note of the 20-digit number printed on the new card before you begin.

1. Transfer your service to another device now. You’ll be asked to log in to MyBell before you can complete the next steps.
2. Follow the onscreen instructions. When prompted, enter your IMEI1 number for a SIM card transfer or IMEI2 number for an eSIM transfer.
3. For eSIM, set up your eSIM as prompted on your device. For a SIM card, insert the new card into your device.

If these devices were purchased from another supplier, and or are locked to another carrier, you will need to speak to them before you can activate an eSIM on your device. Please check out the instructions in these web links:

Yesterday I bought a new phone at a Bell store.  I transferred my SIM at home but now it says it is Not Registered on Network.  The SIM worked in my old phone (Samsung Galaxy S22)

How do I get my SIM registered on my new phone

Hey there @John_M , 

Welcome to the community and thanks for your post.

The community being a peer to peer assistance channel, it would be hard to determine the cause or even see if the SIM/eSIM was transferred properly. 

With this being said, we invite you to check out the above thread for tips and tricks and provide us with more details. 

Let the community know if you have more questions.
