I bought a Glo SIM with the intention of browsing on Glo Flexi with 1₦ per MB. I've been trying to make it work for 2 months.

The data comes up to browse when I buy a data plan, when the data is exhausted, the data signal doesn't come up to browse despite a message coming up telling me I'm currently on Glo Flexi.
I've done everything I could to make it work but didn't work they include:

1. I stopped recharging from the bank, bought a paper recharge card and loaded with *123* but couldn't browse.
2. Dialled *108*1# *108*2# *108*2# To subscribe, unsubscribe and subscribe again but no effect.
3. Changed APN from Glo flat to Glo secure to Glo direct, to Glo flat again, data signal didn't come up to browse, changed to blackberry.net data signal came up but didn't browse.
4. Texted PAYU to 127, but got "the plan you're in is not compatible with your data plan"
5. Changed tarrif plan from Yakata to Glo bumpa still no data signal.
6. Called their customer care. They kept telling me to do all these things I already did.
I wanna browse with my airtime but not working.

Any help will be appreciated cox I'm planning on dumping the SIM.

how far now? can you browse now?
