500mb upgrade when get to level 2

Yes you can.

You need to wait for the next billing cycle

Yes, you'll also be able to use your 250 Mb later.

the same to me.

You can aim for level 2 before the next billing period and apply the 500 MB right away.

Then aim for level 3 for the following month, you will have both 500 MB and 250 MB.

LEVELS (Level - Points required - Reward)

• 1 - 0 - 250 MB upgrade and 500 MB perk
• 2 - 1,500 - 500 MB upgrade
• 3 - 4,500 - Free voicemail, $1 internet upgrade, unlock 2nd upgrade slot, $1 internet upgrade
• 4 - 9,000 - 200 MB upgrade, $1 internet upgrade
• 5 - 15,000 - 300 MB upgrade, $2 internet upgrade, unlock 3rd upgrade slot

Yes but it will only be effective at the start of your next billing cycle.

At first you will be able to only choose one but later on with the level upgrades, slots will it become available which will make you be able to combine both upgrades.
