thank you, but it haven't any solution for that! i have a way but i'm not sure about that, and that is: if my operator name is null, it haven't simcard, but i just have one tablet and can't test it, all of devices without operator name, haven't simcard, and the emulator operator name is "Android" — Amir Hossein Ghasemi, Aug 14 '13 at 06:35

You can use Device id too. See here How to get the device's IMEI/ESN programmatically in android?

AFAIK, wifi-only devices(Without any SIM support) will return null as id. You need to test it once though.

[EDIT] You can query packagemanager to see if the device has SIM support (or telephony support)

PackageManager pm = getPackageManager();
boolean deviceSupportsSIM= pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY);

You can check PackageManager to see more constants that can help you identify if it's a GSM or a CDMA device, in case you need.

Yes. This is the most standard way. Not sure about emulator though, as I believe they have some emulation for telephony. I will be surprised if it returns false for emulator. – Aman Gautam Aug 14 '13 at 12:00
