I have a Japan A2903 model iPad (believe this is iPad Air M2) and need cellular data.
Tried couple of SIMs connection didn't seem to work .
How do I know what SIM from which Telco is compatible for this device?

The majority of mobile phone SIMs are not correctly provisioned for use with tablet computers. If they work at all, they may not provide access to the full range of cellular services. This is not a limitation of the iPad, but of the Cellular network provider.
You will require either an eSIM or physical DataSIM explicitly provisioned for iPad or mobile broadband (a.k.a. MiFi). Check with your preferred Cellular Carrier for an plan suitable for iPad.
Be aware that an iPad, whether a Cellular model or not, is not capable of directly accessing Cellular Voice or SMS/MMS Messaging features. An iPad with either WiFi or Cellular connectivity alone can only access IP-data services. If you have added an eSIM/DataSIM and Cellular plan to a WiFi+Cellular model of iPad, the number associated with the SIM card is only used to identify your account for billing purposes. This number is not used for making calls or sending messages.
