How Long with 3UK SIM Work for Incoming Calls Without a Topup? -

I bought a Three UK SIM off of ebay, sent to me in the US. I noticed that without any topup, incoming calls go through (free USA roaming, so no charge for incoming calls to the US.)
Anyone know how long I can use the SIM for free incoming calls without a topup before it gets shut off by the carrier?
