The Globe and Mail reports in its Wednesday edition that the CRTC has warned Telus that a new fee the company plans to charge customers could breach the regulator's ban on activation charges to take effect later this week. A Canadian Press dispatch to The Globe says the CRTC issued a letter to the carrier on Tuesday saying it hoped the matter could be resolved before the rule change kicks in Friday. It comes a day after Telus distributed a memo to employees saying it will begin charging customers up to $25 when they switch to a new SIM card. Telus insists the fee doesn't violate the CRTC's new rules. In the document, Telus said it would introduce a $15 SIM purchase fee for new activations. The one-time charge, which would take effect Thursday, cannot be waived, the memo said. Customers would see it on their first bill, both for physical or eSIM purchases. The memo instructed staff not to encourage customers to call in to have SIM cards refunded or credited "for any circumstance." It also said an additional $10 shipping charge would apply in some cases. Telus's memo said the charge is meant to cover "real costs" associated with providing a new SIM product to a customer. Telus earlier eliminated an $80 connection fee.
