Send SMSs anywhere in the world for FREE from your mobile phone! Site updated....


Mjoy is an unbelievable service and I use it daily!




Granted, MXit is (very) gr8, but for those that aren't 'hard-wired' (logged in) to MXit all day, SMS is more accessible (but, until Mjoy, more expensive).



I see the site has just been upgraded and I couldn't find the login button on the new site (I could only see a 'Join' button) on the http://www.mjoy.com/ page. :eek:



I managed to find a (temporary, I hope) workaround.... by entering my Country and Cell number, then clicking on the "Join" button,
then an SMS was sent to my cell phone.
I followed the link on my cell phone and the system complained that the cell number was already registered - I clicked 'No' to keep the exiting user,
and then I was taken to the 'Change password' screen.
I entered the old password (twice) and I was then taken to the Mjoy main menu (and I could send SMSs again).




BUT, I logged out again, and then the Login button was still missing.... do I need to go thru the "Join" process again??

See here for the orginal HTT MJoy post: Send SMSs anywhere in the world for FREE! (OK, you pay less than 1c for the GPRS costs)

Update: Mar2009: see comments below which include statement from Mjoy indicating that their service is primarily for mobile - so PC users cannot use their browser to login.

I have heard of colleagues using Firefox to login successfully though.... must be an Add on, because virgin installations of Firefox are blocked from logging into Mjoy.

Here's a dump of add ons from a PC with Firefox that does allow logging into Mjoy:

Update: 06Apr2009: Seems like all good things come to an end... Mjoy have now restricted the SMS sending of messages to max 5 per day. I got this error message when sending an SMS:
"Sorry, you can currently only send 5 messages per day. To help increase the daily amount of messages, please click on advertisement when using this service."

They still need to modify their message on their registration page which still says;
"Send unlimited FREE Text Messages to any mobile phone in the world. Enter your phone number below and we will send you a message with a link to our service."

Can your PC handle numbers with 27 zeros on the end (1 octillion) - don't worry, they've just knocked off 12 zeros (trillion)

I feel for the poor Zimbabweans who have had to deal with numerous currency changes over the past few months. The latest is the removal of more zeros - this time 12 zeros.
See below for a table showing the names of these large numbers eg: Quadrillion = 1 with 15 zeros and Quintillion = 1 with 18 zeros.
Dealers in Zimbabwe had to carry around tables like this to understand what the figures mean!



Here's a report by Martin Fletcher in Harare (published by The Times (UK), on 3 February 2009):

Nothing to lose: how Mugabe’s banker turned Z$1,000,000,000,000 into Z$1

Gideon Gono, widely regarded as the world’s most disastrous central banker, knocked another 12 zeros off the Zimbabwean dollar yesterday in an attempt to bring the national currency back from the realms of the fantastical. In a stroke, the governor of Zimbabwe’s Reserve Bank slashed the street value of the Zimbabwean dollar from $250 trillion to one US dollar to 250, because the computers, calculators and people could no longer cope with all the zeros. To counter an inflation rate that economists now estimate to be 5,000,000,000,000,000,000,000 (five sextillion) per cent, Mr Gono has now struck 25 zeros from the plunging national currency since August 2006. One American dollar would now buy Z$2,500,000,000,000,000,000,000, 000,000 (2.5 octillion) had he not done so.

Mr Gono’s announcement came just weeks after the introduction of a Z$100 trillion note, the latest and biggest of 35 denominations that he has brought in since January last year but only enough yesterday to buy half a loaf. "The zeros are too many for our machines to handle," said Obert Sibanda, the chairman of the Zimbabwe National Chamber of Commerce. Mr Gono is now ordering Zimbabwe’s red-hot printing presses to produce seven entirely new bank notes ranging from Z$1 to Z$500. Economists poured scorn on Mr Gono’s announcement, pointing out that four months after he knocked ten noughts off last year they had all returned. One Western diplomat suggested that the governor’s reputation would be buried at "Zeros Acre" – a play on Heroes’ Acre, the name of the national monument to Zimbabwe’s independence leaders.


Tony Hawkins, a University of Zimbabwe economist who taught Mr Gono 20 years ago, observed that the governor was not the student of whom he was most proud. "He was a good student but forgot whatever economics he learnt when he became a political player." Mr Gono is not a man plagued by self-doubt, however. In an interview published in Newsweek magazine yesterday he said that he printed money simply so the Zimbabwean people could survive but the rest of the world was now following his example because of the credit crunch. "I had to print money," he said. "I found myself doing extraordinary things that aren’t in the textbooks. Then the IMF asked the US to please print money. The whole world is now practising what they have been saying I should not. I decided that God had been on my side and had come to vindicate me."



Mr Gono, 49, recently published an autobiography – sold only in US dollars, in violation of his own currency regulations – in which he claimed that President Bush had offered him the post of senior vice-president at the World Bank last July. Economists said that knocking off 12 more zeros would make not the slightest difference because hyper-inflation would render the new denominations equally worthless within weeks. The demise of the Zimbabwean dollar will also be hastened because last week the Government sanctioned the use of the US dollar, the British pound, the South African rand, the Euro and the Botswana Pula as legal tender. In effect, Zimbabwe now has two parallel economies, one using foreign exchange and the other using the increasingly irrelevant national currency. This is exacerbating the problems facing Mr Mugabe’s faltering regime because his security forces and the civil service are paid in Zimbabwean dollars. Soldiers have rioted on the streets of Harare, and most of the public sector – teachers, doctors, nurses, municipal workers – are on strike, demanding to be paid in foreign currency.



Morgan Tsvangirai, the leader of the opposition Movement for Democratic Change, is trying to make Mr Gono’s removal a condition for his party joining a unity government next week. Mr Gono’s record is also coming under fire from within his own Zanu PF party. But asked by Newsweek if he considered his governorship a success, Mr Gono replied: "I am modestly credited with the survival strategy of my country. No other [central bank] governor has had to deal with the kind of inflation levels that I deal with. [The people at] my bank [are] at the cutting edge of the country." He added: "What keeps me bright and looking forward to every day is that it can’t be any worse."

Buying airtime can be done in numerous ways - HandyTechTipper weighs up convenience with discounts

I was looking for a online site that offered discounted airtime for my prepaid cell phone.
I previously used Discovery Vitality's Airtime that offered 10% discount (now discontinued and handed over to
GotPrepaid).
I now purchase from Pick 'n Pay stores or Clicks.

I was looking for an online alternative - and here are my findings...
image
Buying airtime for your pre-paid cell phone is easy - go to any shop and they'll gladly sell you the airtime 'virtual' voucher that you can enter into your phone.
Online purchasing of airtime is also easy - if you have a credit card

HandyTechTipper (HTT) did a search for airtime vendors

Discounted airtime is also a bonus for the end user i.e. buy R29 worth of airtime for R27.

HandyTechTipper's ideal place to purchase airtime would be one that offered all of the following:
i) online vendor; ii) accept credit cards; iii) offered discounted airtime; iv) automated airtime credits.

Click here to download: BuyingAirtimeCalculatorFeb2009.xls

Note: not all vendors have been verified - use at your own risk!

Using the spreadsheet:

In worksheet "AirTimeOutlets":
Use worksheet "AirTimeOutlets" to see a summarised view of what's out there
Look through the offers and use the "ShortList" column to filter the offer that you are interested in and so home in on the offer best suited to your needs

In worksheet "DiscountedAirtime":
Use worksheet "DiscountedAirtime" to see what %age discounts are given.
Look through the offers and use the "ShortList" column to filter the offer that you are interested in and so home in on the offer best suited to your needs.

It seems that the following services come up tops for me:


http://www.airtimeforfree.co.za/ due to the highest discount and 26th voucher free offer [buy 25 of R12 vouchers for R287.50 and get airtime to the value of R312.00 [= 7.85% discount]].
image
http://www.vtime.co.za/ due to the random discounts and specials offered eg: R1,100 for R1,000
image 
Pick 'n Pay and Clicks give small discounts (or ClubPoints), allow credit card purchases - but don't sell airtime online :(

Banks like FNB, ABSA are very convenient (no registration forms), online, 24x7, and transfer airtime immediately.

eBucks: gr8 to use up those bucks for airtime too.

Watch out for those "services" that require registration fee and transactional fees.

So, either go through the pains of registering and paying using EFT (and wait for your topup) to get your discounted airtime,
OR purchase online via your bank for immediate topups (but no discounted airtime).

Update on 7th April 2009:

I would love to be able to verify all the vendors listed but I do not have such funds (and time) at my disposal – for a proper verification of all services I would need to purchase at least 30 vouchers from each vendor and then calculate what the overall costs and savings were. This would (sort-of) then take into account the varying/random discounts and come up with a better comparison. But, even then, random prizes (eg: free cell phones, etc.) could not be taken into account…. I’d say that was an extra bonus that the end user shouldn’t bank on.

I have also noticed that http://www.vtime.co.za/Tips.asp have an ongoing offer of R1,100 airtime for R1,000.

Updated on 14July2009:
MTN users can now buy prepaid on credit (directly from MTN).
See here for more details: ITweb article

Update on 7th September2009:
Another service that accepts credit cards online is: BigTimeAirtime
There's also a small discount of R1 or R2 on amounts over R100 or so.
