Activated 7 days ago on the 50% off promo with data not working on iphone. After 6 days of waiting, someone got back to me, and data still not working. They say to change the apn from isp.mb.com to sp.mb.com
The problem is the apn is fixed in iPhone and any change I make just reverts back to isp.mb.com
Customer service agent just told me figure it out with device manufacturer!
This is completely unacceptable! Does anyone how to change the apn permanently on iPhone?

Ahh that sucks. Sorry about that.
My previous provider has a 2-month period where you can basically hop back onto your previous plan. Maybe check if that's something that's available for you?

It's so hit and miss what agents you get

Just incompetent, they cancelled my service and refunded me. So now I have no service and can't get the 50% off promo anymore!

@Djdkdkkf I got an agent to reply to me. They added a $5 voucher to my account to try a new eSIM, and that one actually worked properly.
Something must have gotten borked the first time around due to the overload on the servers... some validation probably never happened for data or something.
Wanted to let you know. Perhaps you could suggest this to your agent?

@Cboivin @Djdkdkkf usually we advise to make sure PM is the only active sim (remove old sim card and disable other eSIM). Then Reset Network Settings after a device reboot
Last, go to Settings > General > About. If an update is available, a prompt to update your carrier settings will automatically appear.

@softech How does one update the carrier profile to the latest version (on an iPhone, in this case)?

No solution to offer, but I am in the same boat. Data not working, voice & text OK. On an iPhone as well, so same result as you if I try to change the APN.

@Djdkdkkf the APN you have changed is for Hotspot sharing, not Mobile Data
The Mobile Data is controlled by Carrier Profile which you have to update to the latest version
Then Reset Network Settings after a device reboot
If issue persists, please open ticket with CS agent :
