Advice on travelling in the USA

[NatSoSure]

Hello everyone.. I need some advice.

I have a Pay monthly contract, Im travelling to the USA end of April, and I just had a Bolt on applied for £6 per day.  I have unlimited text and calls and data... but My spend cap is set to zero now..

Is this a good or bad thing?

My phone stopped working last time I was there and I kept hitting caps but I didnt have the Bolt last time..    so this time, I just cannot sit without a phone.  Will it be okay?

How does barring occur on a zero spend cap?

Do I need a higher spend cap so My phone wont stop working? 

Any People travelling to the USA that have advice on the what they Always do, to ensure it doesn't cost a fortune and the phone always works..  Id appreciate your tips and tricks. 

Thanks

Nat

Spend caps don't apply to O2 travel.
