Hello tcjohnwh,

The Muama Ryoko portable WiFi router uses a prepaid SIM card, and you can use a SIM card from Viaota or another provider. If you use a Viaota SIM card, you can contact Ryoko’s support by email to increase your data volume during the current month. Other providers may also offer a way to top up your data volume during the month.
