I got this sms a couple of minutes ago on my MTN sim:100 MTN-2-MTN SMS for only N50. Simply text SMS to 321 to buy. Start texting! SMS Offer valid till 18mtn11 Sept. So, that’s it from MTN. There seems to be a strong competition among Nigeria’s Network Providers. That’s one of the advantages of having many players in a sector. It forces out what’s really obtainable in such sector. So, start texting!
