Galaxy Tab and Galaxy Ace stopped receiving emails from yahoo. Can see yahoo account but no new emails. On both, deleted accounts, cleared cache and re-set-up. No change. Ended up deleting account from Galaxy Ace and access yahoo thru app, but want Galaxy Tab to be normal again. Have another email account on galaxy Tab and it works fine.

the galaxy tab will be locked to the provider you got it from, which is why your sim isnt being recognised. You will need to unlock the tab to allow it to accept any sim. To get it unlocked you need to request an unlock code from Telstra
