Thanks for using the forums to get this question answered about your Son's SIMO.
We would not be able to process this here as we're not a mobile sales or upgrades team, however I can give you the contact numbers for them 🙂
Please call 0345 600 0789 or text 0753 301 6422 to chat about getting a SIMO purchased and sent out. I also have a link here to our mobile webstore so you can browse what different offers we have available before you call.
If you have any other questions about this please let me know.
