I can not use LG G Pad IV 8.0 with my speakout sim card | Phone/Device Issues and Features | Consumer forum

Recently I bought an unlocked LG G Pad IV 8.0 tablet and I want to use it with speakout sim card for text message now and data plan later. I installed my speakout sim card, but there no speakout service (can not connect to the speakout network) in my tablet, I only can receive text message, but can not send text message. I installed the virgin mobile sim card from my friend, my tablet works well and show the virgin service that I can send and receive text message. After did online research, I found it should work for rogers network, but it rogers network can still disallow (sometimes) LG G Pad IV 8.0 in their networks using IMEI ranges. (For detail see: https://apn-canada.gishan.net/en/apn/rogers/lg-g-pad-4-80-fhd ).

My question is: Is it my tablet is blocked by rogers networks? And Is there any way speakout can unlock my tablet?

Thanks
