Moving Number from AldiTalk to O2


Forum|alt.badge.img

Hello,

what are the steps to transfer my PrePaid number to o2?

As I understood, first I need to ask AldiTalk to release my number, right?

What happens after that?

 

Here are some more questions I want to know before deciding:

  1. How long is number active if I do not add balance to PrePaid number? Is it 4 month? Can I add just 1 Eur every few month to keep the number? on Aldi minimum to add is 5 Eur. The reason is that I have a number also from my job with unlimitted everything. But with my personal number I’m signed-up to many important things.
  2. Will my AldiTalk balance be also transfered to o2? Or I have to ask Aldi to send it my bank account?
  3. How long does the switching usually take?

Thanks and BR

Send an SMS with the text "Bank" to the short code 56656 (free of charge) from the o2 prepaid mobile phone you wish to top up.
We will immediately send you o2‘s bank details and your personal payment reference via SMS.
Use these details to transfer your desired top-up amount (e.g., 10 euros).
Make sure to enter the payment reference correctly; otherwise, the payment may be returned.
We will notify you via SMS as soon as we have received the funds and your prepaid account has been topped up.

Important: Only use the IBAN listed in the table below:

beneficiary

BIC

No 6 months. 

Can I add just 1 Eur every few month to keep the number? on Aldi minimum to add is 5 Eur.

Also just 1 cent is possible. 

Will my AldiTalk balance be also transfered to o2? Or I have to ask Aldi to send it my bank account?

No, the second way. Ask Aldi to send it to your bank account and add it to O2 manually. 

How long does the switching usually take?

I am not sure, maybe another user can confirm it, but I think about 8 days. So I would prefer to buy the O2 Prepaid card, activate it, transfer the number (use the old card until it is finished)

Hello ​@o2_Solveig 

Most of questions are answered.

I do have few more.

I have already ordered new O2 free prepaid sim card.

As I understood the process, the sim card will arrive with a random number, right?

And at what point and how do I have to notify o2, that I need my AldiTalk number to be transfered to the sim?

Also… during the ordering the prepaid sim card, o2 did not allow me to order it under the e-mail adress, that I use for o2 (I have a o2 home internet).

Will it be possible to have everything together under one account?

 

Thanks

Hello all,

Today my number has been moved to o2 as a prepaid card.

Is there possibility to have both, my prepaid card and my home internet under one account of meinO2?

Currently I have two seperate accounts.

I could not find a way to add my prepaid to home internet meinO2 and vice versa.

No, that is not possible. Prepaid cards always have their own separate accounts and cannot be merged into postpaid customer numbers.

@5G_Tester 

Hi,

I just tried to see how can I upload 1 eur, or as you mentioned, even 1 cent is possible to add on balance.

I only see the options are starting from 5 eur with all the payment options.

Can you please let me know how can I add 1 cent?

Thanks

Hello ​@Bumer 

I sent “Bank” to 56656 and got bankd etails, but the IBAN is different.

I use N26.

when I add the IBAN I recieved, N26 correctly finds the it belongs to “UniCredit Bank”, but it says “We couldn’t verify the account”.

As a name of recipient I added Telefonica Germany GmbH & Co. OHG

Then, I still tried to send 1 eur and the transfer has failed

@Bumer 

With your IBAN it did go through.

How long does it take usually before I see it on my account?

as reference I used my number and four digit code I received when I sent “Bank” as sms.

 

It is however still strange, why does o2 send incorrect IBAN number with sms :)
