Difference of the USIMS

[smlee]

I have 2 USIM and 8 USIM.
2 USIM cards was in test phone from the time of receipt.
When i use 2 USIM card at other device(no test phone, embedded device), they work well.
But 8 USIM don't work at other device. They only work at test phone.
How can i use the 8 USIM at other devices?
What is the difference of the USIM?

Hello smlee,

Can you please provide us the username of your HostedCore account?

Regarding the USIMs difference, there should not be one. All SIMs are from same batch, but we will look into it after we recognize your order/product.

Thank you in advance
