Prepaid has 100 minutes a month plan with unlimited texting for $15. If on auto-pay a tiny bit of data is included.

There are a few different options for adding a talk/text only line for a kid. Here are a few possibilities:

1. Prepaid or pay-as-you-go plan: Many mobile carriers offer prepaid or pay-as-you-go plans that can be a cost-effective way to add a line for a kid. These plans typically do not require a contract and can be activated on a basic phone or smartphone that the kid already has. You simply pay for the minutes, texts, and data that you use, so it can be a good option if you don't anticipate your child using the line very often. Take a look at Public Mobile

2. Family plan: If you already have a family plan with your mobile carrier, you may be able to add a line for your kid at a discounted rate. This can be a good option if you're already paying for multiple lines and don't want to switch to a different carrier. Telus offers this.

3. MVNOs: Mobile Virtual Network Operators (MVNOs) are companies that lease wireless network capacity from the major carriers and then resell it to consumers at a lower price. These companies often offer very affordable plans with talk and text only options. This would be Koodo.

Overall, it's a good idea to shop around and compare plans from different carriers and MVNOs to find the most cost-effective option for your kid.

Any pre-paid plan avoids an accidental billing bomb… once the minutes and data you paid for are used up, usage is cut off. No chance of accidental roaming or other surprises.
