No expiry date is printed on the sim but sim number. These don't have top-up cards included which usually have expiry dates. However, Most unused sim cards usually only last about 6-12 months before the number gets recycled on most networks. I wouldn't risk buying so too far in future that long since you don't know how long the resellers have had them in their stock inventory. Something like 3+ months is fine but I wouldn't leave it far too long in the future.

I didn't even manage to use more than 2x 200 MB as I had use of Wi-Fi. No chance in hell you can even use 1GB for What I had used it US, for which I paid £10 for 1GB to use in a month. I had a 1GB Trio , and just managed to use 200MB of this, then another 200 MB of a Data Reward Sim, just about used 150MB.
